So I got GG MF as a reroll the other day and finally got to try it... its really... bad.
No disrespect to the team behind it but after trying this skin I have to say its considerably the worst of the ultimate skins. The visual effects are terrible and bland compared to other ultimates, and the fact that the unique feature (changing weapons) is restricted to use at the fountain really puts this skin far behind the others. I can see hardcore MF fans getting it but in my honest opinion, it's really bad. I'd tier it as a legendary skin but not an ultimate.
Honestly, it might get a pass if the unique feature wasn't so restricted like the others. It just feels overall rushed and you can tell that at some point in development some very bad ideas were pushed onto the skin. It's a shame really, it has potential, it really does, but in its current state, the GG MF skin is just plain bad in my opinion.
