Good Way to Tell A Character Is Over-Powered....
Is by the fact their variant is the only one you ever see people playing. Every time I encounter a Brainz, it's Electro Brainz. Nearly every time I encounter a Corn, it's BBQ, Nearly every time I see a mech, it's the fire one, and now nearly every time I see an engineer, it's that roady one with the pulse vibration.
Now, why is that???? Everyone can have favs of course, but people are also going to pick which ever character is the strongest. That too is a major imbalance IMO. The variants can have different abilities, but if one is so overwhelmingly superior to the others, why would anyone ever bother with the others? And why did the devs make it this way. Didn't they want all characters to shine?
I think every variant should be strong and weak in their own ways, but not better.
