Ride the Lightning
This sounds fine, as in the interview it was explained that it only halves proc on players. This naturally prevents people using siege/rabbits etc to break combat…. Also dragons etc are not considered standard bosses (as was shown back when condition damage meant nothing to them!).
I think if it worked this skill would simply be back to being abused, just more situationally…
You can still obtain the 20 second cooldown by hitting ambient white creatures. I am still hitting world bosses for damage with the skill.
I’m not sure if the cooldown procs correctly on Engineer turrets, haven’t tested it yet.
