-i agree that armor lock is frustrating but u can counter it by using them as bait, as for the rest of your supposed changes,
-camo is fine the more clustered your radar the closer he is to you,
-dont really pick up the PL but when i do never had a problem getting some kills,
-i dont like bloom but its w/e cuz since kill times are reduced and shot are random u dont have the one man killing machine that was prevelant in halo 2 and halo 3, and becuase of that teamshot and teamwork are needed and therefore promoted,
-the drm/snipe vs vechicles is fine cuz if u think back to halo and halo 2 vehicles were essentialy invincible unless u had rockets or your own tank or banshee, so that makes since u can teamshot and destroy,
-the betrayal system is fine cuz ive accidently killed teammates when they waltz in front of me sniping and been booted instantly, it was there fualt but im taking the punishment so instant boot is a no
-grenades maybe op but if u ever played halo ce, ud realize they are nowhere near as powerful, if anything shuld be fixed about grenades its the inconsistent bouncing, like when they tend to stick to the flour in stead of bouncing properly and the random trajectory when u throw them, that can be rather frustrating
- those are just my thoughts about your post
