I'd like to see the following changes to the assassin trees:
death field now acts as smash: each tick of creeping terror now adds 25% to DF's base damage, up to 100%. each tick of discharge adds 25% to crit chance, up to 100%. using thrash, maul, or shock lowers the cooldown of deathfield by 1s. remove the thrash crit damage talent and add a talent that reduces the cooldown of DF by 3s.
creeping terror now resets the resolve of the target when it roots the target. recklessness adds 4 stacks of creeping terror base damage effect.
that is all
That would get you almost 10k death fields. That would be way too overpowered.
