You might want to check out how your healers are healing. If they're all just spamming big, slow heals, of course your tank is going to die. You need some of them to be aware of when to shield MT, use quick heals like FoL, flash heal, swiftmend etc. and make sure they always keep HoTs up on the tanks. If you think healing's fine you might want to look at whether or not your tank is shield blocking properly. If all else fails, just suck it up and use a couple ironshields for your first few kills. They make a world of difference.

Assign 1 person to heal the raid and the rest on the tanks. Having the healers heal themselves at the same time after a shatter is begging for a wipe.

A shaman is good for this.

Was working normally for us today at least, I took all Hurtfuls except one that happened when I wasn't in range after getting thrown particularly out of the way by Ground Slam. Luckily that one hit a feral druid that had just gone Bear form to feral charge to Gruul so it wasn't really an issue.

I can also confirm that Hurtfuls appeared to be working properly as of last night. I was a very close 3rd on threat for a large portion of the fight and did not have Gruul swing at me until ~8% after the OT had died.

What's the minimum acceptable DPS for Gruul? 600 for the DPS classes? I'm sorry if this has been asked before, it's a difficult thing to search for (and browsing through WWS would take ages)

Killing him in 14 growths (a good goal to shoot for for a first kill) requires something like ~8500 raid DPS. Figure out how many DPSers you're bringing and do the math from there, it's going to vary from class to class and on gear level, if it's your first kill.

This has been happening ever since the 2.1 patch. We just have two OT's now. Of course this really hurts the aggro generation of them so our melee really have to be careful.

does not seem to be fixed with 2.1.3 …

I can't say if 2.1.3 rebroke it, but it was most definitly fixed before that patch. The past several weeks my guild has spent lots of time in Gruuls and had no issues with anyone other then the second highest threat in melee range eating hurtfuls.

Did not check last night immediately following the patch however.

Gruul's hitbox (especially when he grows considerably) allows melee to hit him from outside of what Hurtful calculates as melee distance. The OT must be careful to remain inside melee distance, which in the late fight can be entirely inside the targeting reticle, otherwise the Hurtfuls will land on someone else.

For what it's worth, we put in 6 attempts on Gruul last night and I never heard one complaint about him hitting the wrong target with Hurtful Strike. The last time the ability bugged, it was blatantly obvious because no rogue would survive past about growth two, despite vanishing on every cooldown.

Unless it was changed in 2.1.3, Gruul's hitbox does not grow when he does. At the beginning of the fight you can attack him from what looks like ~10 yards away, however, after 8-10 grows, max melee range is almost inside his body.

Another annoying thing about Gruul's hitbox: when I was tanking him, I had to apply my own thunderclap and demoralising shout. For the latter growths, it was almost impossible to land one since his center is apparently out of range. I had to run at him, which caused all sorts of problems.

I only skimmed the first page or so, but has anybody mentioned that this damage is mitigated by armor? Because it is. In fact, all damage in the Gruul fight is mitigated by armor. So make sure any decisions people can make involving armor involve "more", not "less". Inner fire, Devotion Aura, etc. Anything that doesn't severely inhibit your ability to do your job.

Shatter in no way appears to be mitigated by armor. With the exception of special cases like warriors in defensive stance(because it's a damage mod not an armor mod), every shatter I see is mirrored between the two people getting it, no matter their respective armor levels. Do you have evidence to the contrary?

I think he's just referring to Cave-In, because you wouldn't think at first that it WOULD be physical armor-mitigated damage. Cave-In also ramps up with growths.

This post is indirectly related to shatter. Last night while doing Gruul's, I decided to test a theory related to Ground Slam. In theory, I would think one would be immune to ground slam if your not on the ground when it happens (ie in the Air). Using Deadly Boss Mod's, I was able to avoid the bounce of Ground Slam on a few occasions. What I did was time my jump when I saw Gruul Jump into the Air (watching the countdown timer to know when to get ready)...when he was at his peak, I would jump and thus be in the air when he landed on the ground. I was able to avoid the bounce all together. Has anyone else attempted this?

That sounds like the Knockback that the tiger boss in ZG had. Some people would swear that they could juke it by jumping before he landed, I could never get the hang of it myself =/

Unable to find an answer anywhere else, although I imagine this is a rather obvious question, but here goes:

Is Grow multiplicative or additive?

Based on first-hand experience, I'm assuming it's additive.

I've never been bounced if I managed to time my jump to be in the air after the castbar timer ends for his ground slam. Takes some practice and a good, low-latency connection.

Jump too early and you land before the cast actually goes off. Too late, and you get bounced as well. It's only a 1.5 second cast so you don't have a bunch of room for error.

Has anyone else tried this? Will try in my next Gruul run.

It's amazingly variable. Last week, I couldn't avoid a single ground slam. Last night, I avoided all but two of them.

Unfortunately, I think it might have more to do with jumping off of something rather than just jumping alone (unless the mere fact that I was airborne for a longer duration was the factor).
