Why is it OP firesparks? Got any replays were a AEC has wiped your entire army as a shock unit?
440mp+65 fuel for something that deals less damage than a T-70 and dies just the same from two pak shots.
Put a shrekked volk in a building and then suddenly this "Stuart on steroids" is hopeless.
Really it's a pretty dumb comparison when the AEC has less health, no instant crew repairs, no working stun/snare and is more expensive
