How has playing your main affected how you play your alternates?

My keys are always similar (except for my Brawler, too many attacks). Attack on X, pickup on Z, jump on C, a mob attack or mobility skill on D/V, Booster and whatever other buffs on A/S/F/PageDown, pots on Delete/End, etc.

Really, since I'm a jack-of-all-trades kind of guy, I can stop one character for a little while and pick up on another almost instantly, even if the play styles are completely different.
