Only if its really unfair; I'll never pick odd-job in Goldeneye. I've had the opposite experience in CoD as you, though, where I enjoy using all the different play options the game has to offer (that's also how toy level up fastest). I couldn't care less if the community gravitates to the UMP45 or FAMAS, I'll troll them with an RPD or Mac-10 all day, everyday.

There is a related aspect in sportsmanship that I'm really not proud of. In Dota, the way you get ahead and secure a win is by singling out and beating down players who are already having a rough time. It's not chivalrous, and in a game like Dota you know the other team is harassing that player to no end over it. But in high skill competitive games that really is just how it works.
