I dont support this! I further more would like to see a more balanced PVE! You cant solve problems by just sayin "Ye double xp and fine". If PVE would be that frustrating leveling as e.g. a pistol/rifl and know "for fucks sake, dat drohners are 10 times faster" you wouldnt be upset.
Furthermore i would support a makeshift to set PVE damage on all weapons equal so all classes can level or farm on the same speed. In addition lower AoE damage down to 33% so it only would make sense on over 3 targets.
