So far I have seen almost every piece of leather gear with armor penetration on it. This sucks because bleeds already bypass armor. I can only think of 2 reasons for this:
1. Blizzard doesn't care about cat people
2. Our buff in 3.1 is so big that they have to give us useless stats on our gear to keep us from being OP
either way, it's kind of annoying that our first tier of gear is suited for us and our second tier isn't.
currently bleeds do about 50% of our DPS. come 3.1 with 50% crit that bleed increase by 50%. so if we're doing 4k dps now, 2k of that is done by bleeds, in 3.1 it will be 3k.
this means that 50% of your dps is from melee attacks on live, and in 3.1 it will be 40%.
I'd rather not be surrounded by a stat that only improves 40% of my DPS
Note: please correct me if any of the above is wrong.
come next patch armor pen will grant 25% more than it does currently, although with our bleeds critting that will counter balance it and it will only be slightly worse than it is currently.
