Perhaps you should have the option to turn off any locked weapons, not particular weapons in weapon packs, because that would get unfair, but being able to turn off weapons like back roller or shotgun. If you unlocked it, you should have the ability to not use it as well
You shouldn't have limited fuel in practice mode, you should be able to put your tank wherever you want so you can actually practice certain situations. Also you should be able hit more than just the one tank.
Since everyone is complaining about how people with money have an unfair advantage in this game (the deluxe package). Well, how about an even ground? What if the care packages that drop can be any weapon in the game, even if you did not unlock it to start out with. Click plus so kchamp can see this! :D
Mayhap you should still be able to select items during the transition to your turn. I always have to click on weapons again when it becomes my turn and sometimes it causes me to use the wrong weapon.
