I think there are some crucial things that need to be done in order for this game to have a bright feature.
By now it is clear the performance issues will not be addressed, so in order to improve performance on console, disable resource intensive unnecessary effects such as motion blur and high textures.
Make the game free to play and make money of from DLC (which seems to be the money making thing nowadays anyway). That would bring in fresh new meat
Add more weapon options specially for Predator, but also for FT. Add a 3rd weapon (side arm) for FT and add at least 4 weapons equipped at the same time for Predator, allowing preds to equip something like combi, netgun, bow and smart disc at the same time
Add auto-targeting to shoulder cannon (but nerf damage)
Add aim assist to controller players
Fix AI ridiculous health for juggernaut and armored troopers. Fix spawning, xray vision and shooting through walls.
Combine missions to make them longer.
Combine maps to make them bigger.
Introduce 3v12 playing mode allowing Predators to team up
