This is the worst, least informed, advice I have seen in regards to swtor.
Energy regen is tiered.
If you spam abilities you will run out of energy and it will barely regen and your raid will wipe.
3/4ths of the classes in the game use energy.
Also, if you don't move out of fire in the first raid you die. So... yeah. Please continue to move out of fire. We have all seen the streams where the damage from aoe was too high and they all wiped repeatedly.
