blizzard removed that you could get rage/runic in the starting area but for some reason im able to hold the runic power i got outside arena before i join qeue, basicly get full runic power, join 10 sec before arena starts, profit. helps when ya got annoying bitches tryng to pop you and you cant use IBF or AMS having no runic power for it.
Do not join at start cuz in the minute youre there the RP will go away.
