Coming across Treasure Hunter early on in their gaming experience will hurt new player retention once they realize that runescape is so focused on MTX. Bonds for ability bars, bonds for runemetrics, bonds for presets, solomon's for bank spaces, solomon's cosmetics, and a chance-based lootbox interface that injects the game with items arbitrarily, promotions every week.
It's insane that all this is happening in a subscription-based game.
So yeah, reducing the number of MTX in f2p would be good. Removing it outright from the game is better.
