So I think Goliath is good at the moment, but for competitive level play he tends to lack a bit more than the other monsters. It also shows because most people don’t bring Goliath to competitive play. Here is the only thing I think Goliath needs at the moment as a quick fix.
Leap smash: a very inconsistent skill which tends to lack against good players. When using this skill I think Goliath needs to land quicker when falling because it’s too easy to dodge. Also I think this skill could be more useful if the cool down was decreased slightly. I main Goliath and am part of a competitive team so I mean it when I say I don’t even bother with it.
