Can't agree more. Unless there were something that undoes the cockup that is modern Minecraft combat, along with certain favourites making the move, I can't see myself going past 1.7.10 anytime soon. There's no compelling vanilla content that'd make me want to move, either; anything 1.8+ has, I can all but guarantee is in some mod or other in 1.7.10.
Did you try to get used to vanilla combat? I like the new mechanics. In the beginning it is hard but after a while you get used to it and I wouldn't want to go back now
