Just my opinion. Revive gives you that regen force shield does. You need it anyway. Id drop force shield since that spike damage wont be reduced by that much. You'd livelonger with leach healing you. Past that i always thought about getting suppression but in a team of 5 all non high armored enemies die to fast or my commando aoe more than once. Pain is iffy it doesnt raise the aoe damage per level just the initial damage to the target wjich is about the same as a auto attack and is contribution to killing him before the aoe goes off.
