no because having adrush up instantly makes BT not the best buff, and you roll for SIW anywayBut you will have a sub-optimal setup, if you don't RtB for those abilties. The entire set of Outlaw is about getting the good buffs of RtB and then use the rest of your set to its optimal use. To make Adren Rush usefull, you pretty much have to use it during your un-optimal phase, which i just a wierd CD then and goes against all other playstyles.

Well would it not be even better, if you could have the ability to keep yourself from both starving yourself of energy and not capping? I will agree, that being starved of energy constantly feels horrible, since you are constantly waiting for the chance to use abilities, but having way too much energy is still bad.
The entire point of energy is that you should never have infinite amount of it, but you should also have to work for to get the resourses. With the current Outlaw build, they might aswell remove your energy cost when you get 3+ RtB or when you hit Adren Rush.
