I'm thinking 59s or 49s
I plan on making a 59 actually
I cba reading the thread but these points may have been brought up already idc
-59s get sockets, no lvlers in the bracket are going to have socketed gear, and if they do it wont have gems in it so you'll get a crazy stat boost
-With trinkets working again playing around with engineering will be fun
-I haven't heard anything denying or confirming this but if proc gear works in bgs that will be fun
-You can mog up to like wotlk @ lvl 58 and as most know mog = dmg
-All of the crazy gear for 59 twinks takes time to get, you're gonna have to go pretty hard to get it all so there will be like no lvlers with the shit you'll have because they cba putting the big time sink into gearing for a bracket they'll be in for a day
-The higher lvl the bracket the more balanced it is generally, I imagine there wont be any crazy fotm like there is in lower brackets
from a strictly pvp stand point idk if 60s 70s or any pve lvl will be fun for dominating bgs i'd go with an X9 lvl. on paper with this new pvp system 59s seem like they'll have the biggest advantage over lvlers in bgs which is what twinkings all about
