So I'm almost done with my second playthrough. I've beaten it as an engineer and an infiltrator and I want a more combat focussed character. Sentinel seems like it would be an effective character with tech armor and warp, but I hear vanguards are really fun. I've been given advice on other similar topics to just do both but I need to decide which to do first. Any opinions?
I used to regret getting a PS3 over Xbox 360, but not anymore. Not since I heard Mass Effect was coming to PS3.
Vanguard. And you don't need heavy charge to be effective, you just need to be careful.
My recommendation is don't try vanguard on Insanity until you have finished the game once and get the XP bonus. I haven't had more fun with a challenge as vanguard on Insanity in a really long long time. Completely worth it.
