I think we have different opinions, I would never build E8 over the regular Sherman. If you really need AT, you can just build Jackson. If you don't regular Sherman can do most things E8 do, and better.
+ this man gets it. You deploy units to win, slightly better arnor and pen (that barely even matter against p4 and are irrelevant against anything bigger) wont even offset losing HE shells. Its not about easy8 baing bad, this unit just overlaps too much with 75mm. Thats why i proposed to change it into "comet like" tank with similar cost.
