Playing as the predator is fun and all but he needs some fixing.

What sort of fixing? Balance improvements?

Maybe he means fun to play as but not so much playing against.

Yup. Shoulder cannon is still an extremly powerful auto lock-on weapon, but at least it requires you to be near your target (easier to spot the cloaked Predator) or to find a target that doesn't move (easy prey anyway). And the spear gun and that funny pistol are pretty powerful too.

You can dodge the disk people...

Just because you can potentially dodge the disc does not make it a fair weapon in the least.

It's not potential at all, it gets stuck in walls.

Getting stuck isn't a big deal as the predator is able to instantly recall the disc if it should so wish, then throw again for a second try.
