Better Tutorial: Teach the players everything they need to know about the game. From the Basic Fundamentals to the Advances. In its current I barely learned anything about it.
Better UI: In its current state the game lacked button prompts or actions, as an ability shooter lacks any active abilities too many passive abilities.
Better Weapons and Class Modifications: In its current state damage output makes no sense along with the weapons fire rate and customize towards characters, their loadouts and selecting cards or mods makes no sense.
Better Respawn Mechanism for both raiders and antagonist
Better Gameplay/Menu Screen: Seperate the Solo Campaign from the PvP. Allow Solo campaign to be playable without having the player to do something. Remove the MMR system in PvP campaign mode and allow players to choose the difficult level. Put in a comp version where you have 4v4 or 5v5 PvP with the MMR system in a objective base game such as team deathmatch, capture point ect.
