I have a major general account in which I have m3 shaft. The laser is no big drawback and can easily be managed by any skilled shaft user. After the recent update, medium hulls have so much life the a m3 shaft would have to do 12 MUs to kill m2 viking. It has only 205 DP per shot, and it is insufficient to even kill m2 hunter with 1MU. M3 is hardly different from m2. So tank I must increase the power of M3 shaft. The HP update for medium hulls has really disappointed me.
