True, never transtforn kits
But why its better to craft kits only instead of commons
- kits doesn't need space
- you have a chance for rare kits
So the more kits you make the more rare kits you get,
also you can fuse lvl 16 rare puk + 1 common puk or 3 common items to lvl 1 rare puk to max it
Still some times you will need some common items to have better fuse system
