I agree with some facts but I Don't agree that Halo Reach is the worst Halo.The custom game was the best of all Halo and the multiplayer was really nice too.
I agree for your opinion about the armor abilities. I was really disappointed when Bungie put armor abilities in Halo Reach. I hate SO MUCH the armor lock. It is a *noob ability* in my opinion. Each time you are killing someone, he start using his armor lock and he is waiting until there is one of his friend killing you. Then he stop using it. Also, in custom game, there was a lot of kids putting infinite armor ability. So in the match, when they are the last man standing, they use it and don't stop. So all the players are quiting because of Armor lock...I JUST HATE IT!!!!!
when Halo 4 came out, I was so happy that 343 removed the armor lock. But in my first match...there were people using:
invisibility : People were camping with it and were not playing as professionnals.
Promethean vision: That ability allow campers to know where are all the enemies around them. So if there is someone coming in there hideout, the campers will be ready to kill him...This is ridiculous.
I also don't like the custom game. The custom game of Halo Reach is better.
I just hate the abilities and custom game, but the rest is awesome.
