Preds Timer Trap and Other poison like skills help on drop those 100% DD chars to.
The problem here is that everyone is spoiled with having OP skills doing insane damage and the excuse is Templars hit insanely hard so its fair. I like your idea of moving Humans back to the front lines how they are meant to be, cap DD but convincing GMs and players that that's how its supposed to be is another completely insanely hard campaign that will end up in players quitting(cry babies that don't want to fix the game) and/or populating servers again from when it was in the beginning of rohan. I thought of the sell/event price on those DD items to but there's going to be another quitting cry babies raging all over forums about it. So any of this solutions will have to be weight and see whats less bad than the other. My solution to this is a test on event server for as long as it has to be done till it can be fixed.
