the main reason I find the microwave tank useless is twofold. One, it’s gimmick relies on you hitting the same tank multiple times at close range in a tank with very little armor and some hefty weakpoints.
Two, it relies on the enemy being exposed and in a position where you or your team can capitalize on its success. Or finding someone solo. Often times you simply get focused down and die before you can shock anyone out of their tank, and even when you manage to shock someone out it’s not exactly easy to do so when they’re in a spot that actually matters against a GDI deathball. It’s incredibly hard to use the tank effectively, due to its design. If it simply acted as an EMP grenade instead, immobilizing the tank when you hit it, with a longer reload time and perhaps a shorter EMP duration to boot, it would be an effective support unit.
