No, not really. I do it when I'm upset with myself for discipline, only once and when I know I'm in a tight spot. After I lose one medi-gel I tend to play a lot smarter. However, there have been times where I'll gel and someone will start trying to revive me and I never even saw them.
It's a judgement call, for me, and depends on whether we're using mics or not. In the first two waves, it's "Man, I was stupid and careless!! *Self-revive*". On Objective Waves, it depends on if the objective can spare half the team. Regular mid-match waves I usually wait it out.
Challenge Weekends are totally different. I need those points!!

Well it also depends on what faction you're facing. Sometimes even on silver the enemies do get a little stomp happy. There's been a few times where after going down, if I'm out on my own (usually out of boredom to be honest) the enemy doesn't spend much time waiting around to stomp me.
But yeah there have been a few moments where we're late in a game and the team I'm with should go back to bronze and I'll get a bit frustrated and just use a medi-gel to ensure we finish.
Lack of trust in teammates - sorry, but a lot of people are terrible. You've got no guarantee you're in a match with people who are half decent, compared to morons who are going to get themselves all killed. Geling early may seems like a bad idea until the rest of your team gets wiped because they're bad.
Lack of contribution - "Hey, it's cool, I'll just sit here and bleed out while you guys do all the work." Some people are going to gel because they can, and they don't want to sit around on their ass while other people carry them.
Wanting more score - kind of the same as the above, but for a different reason. Time spent down = time not stealing other players kills, man!
I wouldn't necessarily say it's the sign of a bad player, just not someone playing the 'correct' way.
