As we all know,HE or low-penetration AP or SAP can not deal enough damage to battleships,especially on high rank BBs.
Before the update Leviathans,we can kill AI crusiers for RP and research AP shells but after the update,most battleships gets a higher BR to separate from the cruisers,and AI cruisers are replaced by AI battleships too,which means a stock battleship can’t even deal some damage on a AI,that’s too pain too grind.
So my suggesstion is add stock kinetic shell(base fuze HE or SAP) for all the rank V ships and add make stock rank VI and rank VII ships have at least one type of APCBC shell(cuz base fuze HE and SAP also can’t deal enough damage)
