As a player who has been there from the beginning, including consolehockey times, one thing I have learned is that you unfortunately can't rely on EA. For example, I remember being in those NHL yearly pre-release events decade ago when I played 1v1 seriously and developers were already back then talking about Spectator Mode and how has that panned out? Or GM Connected? List goes on.
I have to give kudos to EA tho as the gameplay is much more fun in 25 overall even though I despice gimmicky grudge matches and other useless features as it's pandering to Fortnite-generation and going further away from true simulation which should always be the direction in a hockey game.
Problem is as svetidaje stated, that EA can and will modify X-Factors during the season and we know how great that will go. I can't think any serious esport, where patch is introduced mid tournament. For example, League of Legends Worlds, which is currently ongoing, takes month and a half and obviously they will be using one and same patch that has been announced way before Worlds started.
And yeah I know that NHL isn't "serious" esport compared to bigger ones but let's be honest here, we are paying to play this game and it's not cheap. The less we rely on EA on anything, the better we will be with the league imo.
Banning Big Tipper is a good start, but the more I think about this the more I'm starting to think that we should bring old school hockey back, which would mean banning all X-Factors and we won't have any "balance issues" in the future and we get our pure skill hockey back.
