I would agree with you, most Evil Cole players I come across usually just spam giga punch into level 1, and they keep trying it until they get a hit confirm. Good Coles usually just spam ice grenade or freeze until level 1.
I don't use giga punch at all and still win most of the time. It's more satisfying to hit them with a level 1 after they make a mistake. On small maps I usually aim for level 3. I'm still working getting good with Good Cole but I haven't found many better Evil Cole players than myself that don't spam giga punch. --- PSN: BloodOps "In my book, experience outranks everything."
Same could be said with Parappa. I don't think ive seen any Parappa player do anything new. They all do that same exact combo over and over again where they grab you with their mic, hit you into the air, hit you back down. Constantly that same exact combo. Same with Fat Princess players. And Kat players. :/
