Look, some of the best mechs don't have quirks, and you have now equalized the playing field with regard to differences in module options that exist currently (even though some mechs have more module slots than they can realistically use). In other words the skill tree is a very very minor buff to mechs like the Whale and Timby which only have one weapon module slot currently. Then on top of that you are reducing much needed quirks for a variety of mechs that force them to spend points to get them back while the Night Gyr lost nothing so it can spend its points however it wants without feeling worse off than before.
The skill tree should be as tech/class agnostic as possible because balance should not change between leveling a mech compared to others (at the same "level"). Basically the balance between completely unskilled mechs should be the exact same as balance between fully skilled mechs. Therefore quirks should not be getting nerfed in "preparation" for this change.
