Oh a micro intensive ability that gives almost zero resualts for its role hahahaha, it so un reliable thr shells i expect to pen a panther dont and the ones that do arent suppose to suck at killing infantry so you tell me or go use it
the ability gets E8's penetration to numbers what vet 0...2 zis has and range to 50. It comes with a downside of reduced mobility, but I don't think E8 is supposed to trade with panthers. Instead you have higher chances of penning p4, making E8 pen 100% of times pre vet 2 P4H (OST variant) at any range.
Panther is much less desirable in 1v1 then 3v3 and 4v4, since it has very limited potential vs infantry. So it is not unheard of people making builds with up to five P4s there.
