Um are you sure this is season 2 gear or just the season 1 stuff tweaked (set bonuses changed). My set bonuses didn't change at all so I can't tell, but when I visited the area52 vendor there was only the new healing gear and the names/stats were pretty much the same for warlock gear.
I think that arena season 2 must be on pair with tier6, whats tier 6 ilvl?
That would be criminal. Getting tier 6 gear just by saving arena points for the first season? How many pve raiders will get BT gear by raiding Gruul for a year and then magically turning that experience into T6?
I think instead arena 2 is just a fancy way to describe returning the arena set pieces, which are pretty cool. Although changing the set bonuses every 'season' would be a cool way to bring new flavors to pvp, although none of these set bonuses are what Id call 'creative' or 'innovative'.
