In a game where there is no further progression in a sense of even higher tier raids you can’t give more stuff for free. If there were constant updates each year with a higher raid I would say yes, after some years you need to let people skip a certain step in the game to keep up with other (older) players but since we will NEVER get another raid tier (a financial report of FC stated that there wont be any big changes / updates made for AoC) and the last (highest) raid tier content is already ~2 years old you can’t make even more items easily accessible.
As I said, the RF already killed T3 and T4, the World Boss killed T1 - T2 and since T4 is better than Khitai and unchained gear the RF also killed off most 6 man instances.
You don’t need any AAs, gear, skill or EXP for RF, you can do it with a green geared character and quickly access one of the best armor sets in the game (most T4 sets are better than T5 sets since back then the T5 armor gave rune effects which is now a seperate item that you need to buy).
So no, you can’t give more stuff for free like other games because most of them still regulary get updates as far as I know.
