They introduced Ones mode before all the X-Factors and it was never balanced alongside new gameplay changes so it's a shell of its former self. A shame really, as I was a previous global champ and had some amazing games with people.
Yup, goons began to take over the mode and I think new mechanics will make it worse.
I've probably played Versus the least out of all the modes - You used to be able to do couch co op with friends, not sure if you still can but that can be pretty fun. I wish they would revert the system back so you don't keep getting matched with players using all-star/national teams.
It's easy when you game/cheat the system - human vs human is admittedly way less authentic; I have no doubt your offline experience would be more thrilling.
100% look into leagues, they have bans on certain x factors and most teams want a more authentic hockey experience with dedicated builds so it should be right up your alley
