The time intensive combats are something I did not like and I'm glad this edition moved away from that. The other thing that really bogged things down were all the situational modifiers that would pop up during combat.
A thousand times this.
My group is finishing up a Pathfinder campaign, and right now with six PCs (a cleric, summoner, bard, fighter, paladin, and rogue/gunslinger) all at 7th (soon 8th) level. The group is not caster-intensive (two 2/3 casters a half-caster and a full caster) but my god the sheer amount of +1's they toss around is maddening! "+1 from haste. +2 from good hope." "Did you remember my +1 from bless?" "Oh, I'm in flank, that's another +2 So with all my to hit was a 32. Wait! 34, I forgot my bonus from weapon supremacy..."
If there is one thing I'm done with, its piddly minor bonuses. +1 to craft checks when dealing with stone/metal. Resist cold 5. +2 to hit until next turn. Ahhh!!! I much prefer (and granted, I didn't play long) the advantage mechanic for handling minor bonuses and granting extra dice (like bless's 1d4) because they aren't forgotten. A +1 to hit is forgotten in the cascade of bonuses; +1d4 is tangible and harder to forget. Creature are either immune, take 1/2 damage, or take full damage from a hit. I'm not always looking up what "undead traits" makes you immune to. Its bad for the DM, its bad for the player.
Secret confession: I love this game, but I can't wait to end it to start 5e. Pathfinder is slowly driving me mad...
