All those units are used in high level games your just not high level i guess. The only unit you named off that is pretty much total shit vs someone with good tc is tesla tanks out range them and 5-6 shot them so they are useless pretty much i would mind seeing them buffed a bit. but then there are deso so teslas are practically pointless in high level games pros will punish you for spending money on them. Yuri is the other it can just be ran over or a pack of dogs can rape them... but flak boats, masterminds, apoc tanks, and all else u listed are extremely used. I use them anytime i need them the flak boat owns really nicely apoc/deso push owns allies mass mirage... you need to learn the game mate. Patching the great game would be a sin. Best video game in history. enough said. gtfo n00b jk
