After hearing horror stories about this game i decided to give it a try what needs fixing

Squad managing sucks
Fix: Remove autofill of squads and squad slots
Comment: Starting out the game its a nightmare of musical chairs to put the good soldier in the squads you use

Soldier gambling
Fix: Add the option to use a soldier level up order alongside the silver cost to get a max perk points soldier
Comment: Its annoying and slow

Tier 3
Fix: Make tier 3 fight only 2 and 4
Comment: Litery no reason to play it unless you like stomping noobs or get stomped like one

Squad leveling
Fix: Make all squad require same amount of xp and their first variant
Comment: Too grindy

Gray zoning in tanks
Fix: Extend the death timer to 60 seconds
comment: many times almost killed the tank in the gray zone but died seconds before getting to it

Plane spam
Fix: remove the ability to equip more than 2 plane squads at a time
Comment: To not incentivise suicide runs and give another player the chance to play planes

Tank spam
Fix: Remove the ability to equip more than 2 tank squads at a time
Comment: To give other player a chance of playing a tank

Recoil (in the like 2 guns that have them lol)
