Was just in a game with a PK who was at rep 26, and they were saying there was a weapon for each class at 30 and they were grinding for it, is this true or were they having me on? Google has turned up empty on this one.
There are hero specific rare weapon sets only available to players rep3 or higher. Signified by a star *. That's all I've seen, however I'm not rep 30 with my PK yet.
There is nothing for 30 afaik. The best currently in the game drops from Rep 3 onwards, the Rare Weapon components mentioned above by Alustar that have a * symbol on them.
I'd like to see more gear added at selected intervals past rep 3/4. It would be a nice carrot to chase, right now I'm just going for the Skull engraving at rep 17 after that there won't be much motivation to cap out.
