@Pyrite You're right mostly, except about Allied requiring nerfs, which they do on some units.
Such as Battlefortress, Seal, and certain promotion bonuses for units at the first level, so the spy is not overpowered.
The Prism tank is mostly fine, but needs a greater delay between shots so that Prism tank chrono combination doesn't completely wipe out bases.
Yuri Needs to be changed the most.
Soviets need fine-tuning with their Battle Lab tier units and of course, the Desolator nerf.
