Iron Banner is pretty scrub-friendly compared to Trials but I dunno how it's gonna be with their new loot system coming up.
Provided that the helmet is available I'd say very probable. The stuff is supposed to be able to drop this time and even if you have to rank up to get it you only need to win around 1 in 5 games since you get a medallion each tome you lose that is turned into rep when you win. Hop in a GAF train and you'll be fine.
Ah, that doesn't sound too bad, then. I was dreading something worse.
But they don't sell all armour every tournament? My helmet!
