That probably has more to do with the stats on those items than the ilvl or tier bonus. The problem with the tier bonus is that we want to use Reck with DR, and so if Reck isn't reduced enough to line up with DR, or it's reduced more than necessary, you don't really gain anything out of it. That said, it is slightly better when using Avatar than WB for the same reason.
It's not a terrible bonus, it just isn't amazing either. Running two quick sims, with no change of gear whatsoever:
- With bonus disabled - 83,660
- With bonus enabled - 85,919
- Net difference - +2.7%
- With Avatar it jumps by an additional 1%
Now that's more than you'll get out of changing one or two pieces of gear, but if you manage to change a number of them, the ilvl boost should come out ahead. Obviously this isn't something with which a blanket statement can be applied - every individual will see different results, especially with the awkward balancing act that is Fury stats.
Avatar beats out WB in just about every situation except cleave, and the only time WB performs better is if it actually procs while you're cleaving. For this reason, I don't really like it for HFC, since adds are so short lived and come intermittently. I've tried both, and they perform very close in both simulations and real testing.I guess with only 2-3 real single target fights it's pretty irrelevant in either case. Also hard to know whether to use WB or Avatar, lots of impressive logs with both on many fights, WB seems to have plenty of times where it just doesn't proc on the pull making it a massive waste compared to Avatar. Fury at 100 seems pretty lacklustre, no particular strengths, I guess it has nice 3-5 target cleave if you can tunnel one target to keep the haste buff up.
