I think IB rewards need reworking. At base power 1060, there is no incentive to earn pinnacle gear. The IB armour is just reskin after reskin so, oddly enough, I already have full sets on each character (which I doubt is an uncommon situation to be in).
Game after game, the drops are simply blues (instant dismantle please?) and the odd legendary which, 99% of the time, gets dismantled straight away.
Hows about awarding some upgrade materials?
Either have prisms and shards drop something like every 3 games and 10 games, respectively... or make them purchasable from Saladin for X amount of IB tokens.
PvP players have it tough when it comes to earning prisms and shards as it is... why not increase the incentive to play IB by adding this in?
