Вот что я нашел (на правах советов лучших гранатоводов Империи):

Use Kinetic AOE weapons. This would be using grenades. ALso each TYPE of grenade has its own cooldown timer, which means you can toss a glop, proton, AND cryoban grenade all at the SAME TIME. (doing up to 3k damage inside of a second with NO action cost)
