So I'm posting here because it's well know just how easy it is for a good warrior to shut us down or damn right kill us despite our healers' best effort.
It's also widely accepted that Warrior do a lot better in Arena then Rogues.
Here's hoping Leather arena gear has a lot more armor penetration then Plate... but I somewhat doubt that'll be the case.
So next Season, look forward to Warriors that kick your *** even more and still kill your casters faster then you kill them.
This make me a sad panda. :(
Then again, the 2.3 leveling change means it might be a good time to level my lil gnome alt :(
I dimly remember an argument where rpzip (I think) showed us that EA (and thus, other armor reduction mechanism) were just as good, if not better, on high armor target... I'm kinda hoping you can dig out those maths again zip, because this isn't looking good :(
