So Crevan, those numbers are given that we don't /cancelaura the Reorigination trinket proc correct?

Regardless, the rune proc might be the best time to use energizing brew, as having 0 haste is incredibly slow, and would be hard to recover from if the trinket proceed in an energy valley:

/cast Tigereye Brew
/cancelaura Reorigination (or whatever)
/use Energizing Brew

Thanks for running the numbers, this trinket looks like a lot of fun and pretty potent if used optimally.

Just like Ghostcrawler promised, the Rune of Re-origination is now purchasable from Flaskataur for all your testing needs.

First of all, it's not possible to click off the buff you get from the proc, just as we suspected. Once it it's up, you're stuck with it for 20 seconds.

Now, about "it being up". It was expected that the RPPM nature of the proc will make it quite unpredictable in terms of when you get the buff, but I'm not sure a lot of players will be prepared for this. I've spent about half an hour on a target dummy testing various stuff about it. Sometimes it would take more than a minute from combat start to get the first proc. Sometimes I would get 3 chain procs right after I start attacking. I once went way over 5 minutes without a proc. Now, not getting a single proc for what is pretty much an entire boss fight duration is bad enough, but getting 3 procs when you still don't have any TEB stacks generated might be even worse since ironically, 3 procs in a row at the start of the fight is actually a huge dps loss.

That being said, when the stars align and you actually get a proc at a decent time, it does feel like a boost to your dps. This trinket would force any user to hover at a higher-end of their resources (for us monks, that'd mean spending chi at 4+ and hitting TEB at 16+ stacks) to have a buffer to start using the proc as soon as it appears. Since TEB buff does not update dynamically, hitting it once at the beginning of the Re-origination proc and once more right before its end would be a good idea. As was suggested before, having Energizing Brew available for the proc is really nice, and I expect that t15 2p bonus will also be very helpful (though it's either disabled or bugged in this PTR build, haven't seen a single orb in 30 minutes; forgot to check if t15 4p was working correctly since it wasn't at all in the last build).

If I had to sum this trinket in one phrase, it'd be "very good when you're lucky, frustrating-to-terrible when you're not". The way it is right now, I very much doubt that I'd use it on progression content where I want consistency over a small possibility of awesomeness. On farm, it might be a neat way of trying to get ranked on bosses.

PS Everything we've discussed so far assumed that we're going for mastery as our highest stat. It's generally considered that haste stacking is not a good option for us, but perhaps it's worth investigating just for completeness' sake. If we did go for haste stacking, we'd probably have to drop Ascension for Power Strikes to try to keep the energy in check. At 8500 rating, which is what we'd get in 5.2 BiS, we'd have 12 e/s passive regen, and each Re-origination proc would give us a mini-heroism/bloodlust, bumping the regen to something like 14.5 e/s.

PPS With the same 5.2 BiS, Crit as highest stat would give us around 17.5% extra crit chance on a Re-origination proc. I'll try to do some calculations for both crit and haste stacking to get an idea if it's at all worth it.

As per the OP, 425 poitns of haste are required for 1% haste, while 600 points of crit are required for 1% crit. That's why SimCraft shows a stronger weight for each point of haste rather crit. However, you will find yourself more comfortable at 4-5K haste.

@Mihir did you notice any drop in your numbers and haste, etc? We should have a base 10 energy/s, so while our energy regen will slow to a crawl it shouldn't absolutely stop. The only issue I can foresee is losing that amount of crit, given that crit is multiplicative.

yeah Bem, thats exactly what i was thinking. I was already using my second stack at the end of the long proc anyway. This just makes it so you dont have time to get two off unless you basically already have a 15ish stack and use it instantly. Then put the new one up with <1s remaining. giving you ~24s of the super TEB.
