It is depressing the crap out of me that as a Sentinel there's really only one correct choice of companion - it's far easier to get through quests with Doc than any other companion. Using Kira I'm more or less forced to use every ability I've got and engage in a life or death race against a single elite, whereas if I'm getting healz I can just merrily use a rotation of 3 or 4 buttons and be just fine by the end.
This wouldn't be so bad if Doc weren't so insufferable towards a female character - he will hit on you, poorly, non-stop no matter what dialogue options you pick. No matter how many times you threaten to throw him out of an airlock or feed him feet first to Lord Scourge, he still insists on throwing out constant cheesy pickup lines. I gave the most cruel answers available the entire way through Balmorra, and STILL he wanted to join my crew and my only response choices were three variations on "yes". I do not want someone on my ship who would make me double check my door is locked every night.
Either let me use another companion to equal effect, or let me beat his face with the hilt of my lightsaber until he learns some respect
