I simply liked her in ME1 just cuz I think her and Garrus are hands down best squad mates in that game imo.... Kinda like hands down Garrus and Zaeed are the best combo in ME2 seemingly good with any kind of Shepard and good in any situation. Sentinel Shepard with Garrus and Zaeed = best possible squad in ME2 I'd have to say.... And no I played like that myself, just looking at how the game works... Sure you perhaps could have better combinations at certain specific points in the game, but in general playing just wanting to be able to take on whatever, then that is the crew... just letting ppl know :P
This is truly puzzling for me too. She was the one character I couldn't bear talking to in ME cause she bored me to tears. When I heard that she's making a comeback I just groaned.. about the ONLY reason I liked having her around in both parts was to tell her how **** idiotic her species is. This holds especially true when you get Legion on board and get some new insights into the whole story... blah.. frankly, wish there was an option to just leave her with her people.
