blaming the game for your lack of ability and rerolling ranged.
i play empire so i dont know what you guys have in comparison, TFE is easy if you are not dumb and die on the first boss whirlwind. just move from it when he starts to spin, then easy mode your way through.
BT can be 2 maned with companions so im sure you can do it with 4 people.
KUS is free gear bar the bonus boss where you might have to think.
D7 is a walk in the park until the end computer where you might die if you try to do it with your eyes closed.
You dont have foundry or Boarding party, so i cant comment on your varients.
Go do dailys on ilum / beleivis and get the epic mods if you are struggeling that much you think you have to reroll.
go read strats
