Is Gus worth maxing out?

I am pushing brawlers to max tier and I got bored of playing berry and jessie that I just maxed out. Should I max Gus as he is top of meta but will he get nerfed in near future. If he is getting nerf, then that would be a huge letdown. I recently pushed Melodie, Juju, Shade, Maise, Frank to max tier when they were in top of meta but Gus has been in top for a while so will he get nerfed in near future?

Also which flair to use for questions like this?
