Respawn times are set up and changed individually by capture points on each map; the only maps that can be changed without worry are Capture the Flag maps, and even then you should only really make small changes.
Valve chose every respawn time very carefully, and it helps the pace of the game. Yeah, sometimes you have to sit there for an agonizingly long time, but it's what makes the game balanced.
