EVERY game that introduced perks, class loadouts, and gameplay progressive unlocks has utterly ruined the core experience it was originally based on
Uncharted 3 is the big one that I remember most recently, I have no confidence in hearing this and by definition, the nature of such features contradicts equality. This removes the fundamental of Halo to favour this insane artificial method of preserving MP games (and I dont doubt that dangling that carrot in front of you has overtaken quality gameplay as the means of getting players to continue supporting the game)
I just am not optimistic at all after reading what I read and history has shown me that all my favorite games have crumbled, despite the PR team assuring me otherwise.
It's not perks I even care about, it's the idea of unlocking gameplay altering mechanics through progression, loadouts, etc. I just think that there are better ways to improve the sequel, and I'm just not confident in hearing something like this. It's not personal, but developers like Guerilla Games, DICE, Zipper, Naughty Dog, etc. have all watered down their games in favor of hyping up features that the core community were valiantly always against, and I dont see Halo 4's introductions of perks (however they may be), class loadouts, and progression unlocks changing that.
I miss the simplicity of running up to an opponent in games like Halo where all that was different between us was the guns we picked up, but with things like perks and whatnot it introduced these advantages other players may not have. Personally, I am absolutely burnt out on such mechanics and am sick of seeing them in so many games.
