over a 6 minute fight, at least in my gear, a MH landslide is worth about 900dps in your spreadsheet. When inputting my raid spell crit (30%) and my average deep wounds mh input (8704 per crit), the average damage from a given Avalanche proc would be ~3455 damage, meaning that in order for avalanche to equal landslide it would have to proc ~94 times over 6 minutes.

As it stands in your spreadsheet, when changing avalanche to 5ppm (current version has it set to 2ppm), it gives me a result of ~183 procs per 6 minutes, and that's not including procs from deep wounds ticks (at least as far as I can tell from looking at the spreadsheet). When I account for additional deep wounds damage due to crits (55.11 crits over 6min duration) it appears a MH avalanche is worth ~1667dps, mostly as a result of the gained deep wounds damage which was worth 1329.7dps.

I haven't messed around in-game with avalanche in ages, but if it really does proc deep wounds, then it certainly seems like it would be better than landslide.

Avalanche does indeed proc deep wounds. You can see it in the screenshots below:
I had a normal melee crit (DW ticking for ~590). After the Avalanche crits, the following deepwounds are ticking for ~1010. Note: there are NO further melee crits that could have upped the deepwounds damage.

Avalanche/dw proc - Imgur

Rawr uses .08 as its base reduction for ignite, so even if the munched value greatly exceeds that for DW it still should not surpass the ~1667 value Dave came up with if thats correct

Apparently I am retarded and don't understand the difference between input and output. In the original math I didn't multiply the DW input value by 0.48, so that number is incorrect.

Using the damage values from this parse and assuming the crit chance is 25% (down from 30% in my original math)
the average damage you gain from a proc is 610*0.75 + (935 + (8704*0.48))*0.25 = 1735.73; With that new value, the number of procs needed for it to equal landslide (assuming it's still worth 890 dps over an 6min fight) is (890*360)/1735.73 = 184.59 procs. Interestingly enough, landsouls spreadsheet suggests that over a 6 minute fight, I would expect to see 182.6 procs. However, as mentioned in my previous post, as far as I can tell the spreadsheet is not calculating procs from deep wounds ticks, so the actual number of expected procs would be higher.

It's also worth noting that SMF should gain more from avalanche due to having more hits land per second than TG, meaning it should get more procs. In AoE situations, while I can't back this up with any spreadsheet math, I would think that the value of avalanche would scale much better than landslide, as I was seeing up to 6 simultaneous procs from a single whirlwind during trash last night

Assuming I didn't screw up the math yet again, I think the TL;DR version of all of this is that avalanche has the potential to be better, but not by a whole lot.

What are the thoughts on this new inner rage 2pc vs. old fire proc 4pc? Worthy upgrade, or better to wait for new 4pc?

It increase your HS dmg (since you will never be capped on HS CD anyway, you are only capped by rage) by 33% for 50% of the time (in worst case, dumbest auto-use secenrio). It's a must have.

I recently obtained [Backbreaker Spaulders] and when I gemmed/enchanted/reforged them, I noticed I lost weapon dps but still gained weapon damage and attack power over my heroic t12 shoulders. Any clue why or is this what I should be expecting with that swap?

-Edit-

By the way, I meant to link the normal shoulders, but you get the point.

I figured as much. That was the only thing that came to mind, but I wasn't 100% sure. Thanks.

World of Logs - Real Time Raid Analysis

there are all my wol for randon DS
our raid do have 30% bleeding damage increase debuff on boss, but my deep wound damage only like 8%~10% of all damage out. In 4.2. its like 16% more, so i do think theres something changed. may be the 40% melee damage increase inflenced deep wound in 4.2 but not influenced in 4.3?

I noticed the same, my dw were 9.9% of dmg at a fight with 99% uptime. Until we get some confirmation whether this is a bug or it was an intentional stealth nerf that didn't make the notes we can't be sure about anything.

Your logic is bad.Really really bad.

First of all they fixed dw double dipping since early 3.0. But even if they hadn't done it, the 5% double dipping change would make 16% 15.2% not 9%. To make a change from 16% to 9% you need a 44% decrease or to put it in an other way, if we consider 9% the dmg dw should have been doing then with some mysterious way it was being increased by 77.7%.

In any case warriors seem to be underperforming atm.
