Illum - my commnando >>>>>>>my sentinel.
Suicidal for melee because of so many Imps, you have no chance to do damage before you instantly die. With commando it's far more easier to do damage and kill someone and run away from danger.
WZ - depends. If you have a healer I like both, if there is none, I prefer range simply because I can do DPS more frequently and escape from danger easier.
Still playing both though, hoping they give a bone to JK/SW.
