My disappointment in the E8 and other mediums

ARGO: The E8 has so much potential. I have one and have totally embarrassed T-44s, Tigers, and uncountable heavies in it because they just can't catch it when your running full bore. The problem? It just doesn't have the firepower to back up it's incredible speed and maneuverability. I will state this as an unequivicle fact, If they put the short 10.5 on the Sherman E8 in the right hands it would be in the top 3 deadliest tanks in the game without a doubt.
