Tbh this season was just fine after they fixed the cost of abilities. Well there's many abilities that people use. Like pretty much all Dmen have Elite Rocket and Elite Stick. Forwards usually have elite backhand (cheap) and some sort of forehand shooting. But I've noticed there's bit of variety and that's something I hoped for. Also not everyone uses 183/88 PWF which is nice too.
Don't really see how banning elite abilities would change much. Maybe the backhand ability is a bit OP but there was very little goals for us this season it was the reason for goal. I even missed two very good backhand goals in the Pro Finals even tho I had it activated.
TLDR; I would keep it as is. Goalie abilities I don't understand so cant talk about them.
