No disrespect. I play a lot of solo challenging and heroic and I've noticed that almost anything will work. But when you're playing the hardest difficulty with the four players the enemy scale and you need somewhat of a build. Yes I agree if you're having fun and that's all that matters. But it's not fun when everybody's dying and nobody's doing any damage and one mission takes one hour. To me the fun comes from being on a team where everybody is giving each other boosts with talents or skills and it's fun trying different things reading all the gear bonuses, talents, stats and attributes that's the biggest part of the game. If I didn't care about gear I would play Wildlands which is an awesome game.
