They just need to add Beyond Light (or whatever annual content it is that year) required for trials play. Thats what they did with Destiny 1 crucible is you need RoI to play the main pvp modes and trials. I think the fact that the game is F2P is fine, base game at least. Theres more positives then negatives. But they do need to lock trials behind some sort of paywall. Plus if Bungie starts banning its now the cheaters own money.
