The game need rebalance. Faster upgrade is useless if you have not enough silver and without VIP and more hours of playing you are unable to earn enough silver for upgrade.
Also there are few OP robots without any counters. Ares is too strong, too fast and extremely hard to kill if you know, how to play it. It has strongest ability in the game and there is no counter. Only Hellburner or Mercury can bypass his shield, but there is less chance to get too close to use their abilities. 8 s immortal with 16 s cooldown and last stand makes Ares extremely dangerous. Do you know whats happen if everbody use it especially in full hangar? RIP War robots.
