I am very happy about the changes that have been made to Team Arena Winter Preview. All the changes have been very good. There are a few more things I would like to see changed in regards to power weapons.
Power Weapon/Power up timing - In previous halo games, power weapons spawned much slower then they do now. It feels like right when the rockets or sniper runs out of ammo, the new one starts to spawn. Instead of rockets, caster, and rail gun spawning every two minutes, maybe increase the timing to three minutes. Also, maybe make shotgun and sword spawn 30 seconds after de-spawn instead of 10 seconds
Sniper Rifle - I think three minutes on the sniper is fine, but I would like to see the ammo reduced from 12 rounds to 8 rounds. Many times the sniper still has ammo when the new sniper starts to spawn. This allows the team with the old sniper to get control of the new sniper as well. Either reduce the round count of the sniper, or increase the spawn from three minutes to four minutes.
Let me know if you think these changes would be good, and what other changes you think might be useful.
