Try changing the wx-78 to eat gears to get additional slots?

[whiteking]

Change the wx-78 to have only 4 slots at the beginning (the acceleration element takes up 4 slots, after all, I think it will only be used at the beginning). Add one slot for every 5 gears, and you can add up to 3 to 4 slots (15 to 20 gears)

It can not only make wx78 not seem too strong at the beginning, but also ensure that the role in the later stage is more comfortable in the face of multiple skill choices
