peak times for us alliance its like 5-10 mins for bgs. they get longer as the day goes on but they'll pop pretty much round the clock if you have patience
80s are more prevalent than 84s
arena que length depends on time of day, bracket, rating, etc.
sweet, but how OP/bad are 84s in arena? at 70 the 74s get roxxkilld in a few secs with the low resi(most of the time) but at 84 they got shitloads of health, new abilities and lot more dmg?
84s do more damage and have a lot more hp, but they do sacrifice pretty much any resil so if you can focus and cc them it shouldnt be too bad, at least in bgs. havent done arena in a while but never faced any when i did
