Honestly, why? this ability needs an overhaul, in many to most cases last stand or barrage is going to do more damage then EES, and its the 2 hour once every two hours that's II hours, 1+1 its barely even worth using as an oh S#@& ability, much like the originall DRG 2 hour (call wyvern) the ability either needs to be revamped or move it to a 20min abil and give us a new and relevant 2 hour...
