The very idea behind biotics was very weird, for me at least. You get irradiated with radiation of sorts and then bam - you're a jedi, space ninja or sonic (that exactly how the krogan vanguard looks). I slowly came to terms with the biotics though, since they are a major part of the ME universe. And I agree that the first playthrough is priceless. I lost Grunt and Mordin on the Collector base and I really felt bad, same goes for Padok and Dagg, even though I barely knew them. When I had to SPOILERS sacrifice Ashley on Virmire SPOILERS I just couldn't play the game, I didn't touch it for a day or two.
Anyway my shep is male, custom made, with the badass scar across his eye, Leonidas style, and he's a sole survivor, colonist, mostly paragon soldier. I ignored just about every love interest in the first two games, I was roleplaying this mission-comes-first soldier, but in the last game I was like "Well, I'm probably gonna die so why the hell not?" and I was a fan of Liara from the moment I saw her so yeah, I think you get the idea.
Just started playing on Veteran and making my way to level 60. I'm thinking about making a femshep biotic, but I'm having a hard time. I'll admit, the one that has both biotic and tech abilities sounds interesting, but maybe it has too much abilities? What's your profesional biotic expert opinion?
