Fights in previous editions often felt like matches of Rock 'Em Sock 'Em Robots into which fireworks were occasionally shot.
and thats how we still do it, when it comes to the actual combat itself. we don't use attacks of opportunity or anything that leads to an attack of opportunity. we don't use rules for all those special combat moves in 3.x like trip, disarm, grapple, sunder, blah blah blah. we dont use rules for terrain factors, or square occupation, or movement.
we swing, miss, swing, hit, fireball, arrow, swing, arrow, lather, rinse, repeat.
thats the way we like it.
thats not to say we dont make use of movement, terrain, and all that tactical stuff. we just dont use rules for it. though we play 3.0 rules, we never changed our combat style from 1e. meaning anything goes. we just say what we are going to do, and do it. we don't need no stinkin' rules! the dm assigns a chance. we get pretty exotic and creative sometimes, and dont need a feat, or 4e style power to do it.
the only time we use a combat map or minis is when the combat is so large that our usual narrative style of combat can't describe the whole battle and where everyone is in relation to each other without confusion. like when we are talking 20-30 combatants. we don't use them for purposes of movement or grids or squares or attacks of opportunity.
