You want nothing but Sentinel nerfs, while buffing Powertechs?
Are you serious? Do you even lift?
If you look closely, you should see that the buffs to PT/VG are only slight
in the underpowered trees. Sentinels will still be just as good afterward. PT/VG are only really 'overpowered' when specced into Assault/Pyrotech, as their burst is insane.
