The Mako is actually rather fine as it is now. It has more armour than the Osiris, similar primary arcs and better heavy arcs. Now it is more agile too. I mean, you obviously aren't going to turn your flank to the enemy, except if you want it slapped.
The Geb is also fine. The ship can't fire ANY primaries backwards! If you want it to be useful against Marduks, you are going to mount a mortar on one of them, and you are also going to be killed by a charging Mako with 2 cerbs. Maybe it just needs its turn rate toned down, if it still turns as fast.
And Wesker, if you can't kill an Osiris with your Mako, that's your problem, not of the devs!
