Tying all TRing to the Sagas doesn't make them an optional source of rewards available elsewhere. It makes them the sole source of the reward.
BTW how many barriers are there being added to TRing?
* The Ings are BTC.
* Sagas must be ran Multiple times, so no HTRing at 20. And from the numbers we've seen, there's no HTRing until level 28 or 30.
* Epic and Iconic TR both must be done at the level cap.
* Epic must meet some Karma mechanism.
As others voiced over the weeks, why are you complicating a process when it should be kept simple. And the HTR system is a working! and fairly simple process. Why all the mucking in the mechanics that work in the game? Especially systems that players aren't complaining about!
