After thorough gameplay. SR 91 and Onyx in Free for all, Team slayer, and SWAT. Here are some issues I have ran into.
1.) In Team Slayer/SWAT I have found the spawns to be atrocious. Why is it I spawn in the same area, and be spawn killed consectively. Not to mention after you kill an enemy they can spawn behind you. Another annoyance.
2.) The grenades, need one of two things done to balance arena matchmaking. Either, decrease starting capacity to 1, or nerf the splash damage. Grenade spam is quite annoying, worse than reach.
3.) What is the point of motion tracker when someone is sprinting/spartan charging has already killed you (caught you way off guard)? Increase the range to 25m and it's perfect. Will give ample time to react.
4.) There should be a veto option for maps and ect.
5.) Add BR start Slayer variants. I hate starting with AR/pistol.
Those are the problems, I have encountered and lately, I haven't been excited to play Arena for those reasons. I been playing Warzone much more, spawns seem a bit more coordinated there. Albeit, it can be crazy sometimes.. but the gameplay makes up for it. This isn't a 'rant' but more of a greivance, that should be fixed.
