unremitting is a good talent, but usually the people who say it is a "must have" are people who trinket out of the first sap they receive
its a good skill. it is not the only way to go though, and it is definitely not worth switching for force exhaust.
as far as the thread goes, OP needs to l2p. i can bomb pugs who don't know what they're doing for 700k on VS, but against the premades who are good on our server, i get maybe 400-500k instead
and the arguement of "oh well its hard to dodge when there are 4 warriors doing it" is retarded. you can take any skill in the game, then multiply it by 4 people doing it, and its harder to deal with.
