Adrenaline Problem?

Hi I installed the latest public druid rpg mutator and everything works besides that when you're a adrenaline master it is impossible to gain enough adrenaline to use a skill longer than a few seconsd it drains over 300% faster than its possible to get even with Vortex Sentinels. is there any way to increase how much adrenaline killing a monster gets you?

thanks for the help and oh if you wanna see what i mean my server is ut2004://68.232.171.167:7777

EDIT: Oh and that is with every possible adrenaline raising skill maxed.
