For as long as I've played the game and longer, one of the biggest complaints about LIs has been Legacy Lotto. You get that shiny new Elder King symbol and make an LI with it, and only get 3 majors. Admittedly this was worse with Isengard and before, and Turbine has since taken some steps to address this by making FA symbols easier to get, but the problem persists. The cynic in me says the problem persists because Turbine has yet to figure out a way to fully monetize the solution; the common suggestion of merging all legacies into a single pool won't increase store sales. For example:
I have forged for myself FOUR first age cappy emblems, at a cost of 488 seals and 1600g on AH. In a couple days, I will spend another 366 seals on my FIFTH Legacy Lotto ticket. All four of the FA emblems I've made have identified with only 3 majors.
While the Crystal of Remembrance was a step towards addressing this problem, for some of the classes out there, it still isn't enough. A healing cappy emblem with only 4 majors on it, for example, barely rates a D-minus (unless you want to swap emblems every 2 minutes in the middle of combat--a severe quality of life issue). If a cappy wants to preserve his sanity, he really needs 5 majors...
Turbine could make more money off the LI system (since we know keeping the lights on is what they care about, understandably) if they introduced a scroll to upgrade one minor legacy slot to a major legacy slot, thus giving us a *complete* way around Legacy Lotto through the store. It's not like they haven't already taken a step toward this with the Crystal of Remembrance, though it was an incomplete step. I know I would have gladly paid 995 TP by about my third attempt at an emblem for preserving my sanity, as literally everything i grind out now is with the sole purpose of acquiring an emblem with more majors on it instead of other ways of character/alt progression.
As an aside to those who argue that FA is too easy to get now (a criticism with which I agree somewhat--given that I even CAN grind Legacy Lotto tickets like this--before RoR HA!): if they sold legacy certainty even a single FA symbol could be made into a "dream" LI once you had it. Now, there is nothing more than the crushing feeling of defeat upon getting a losing Legacy Lotto ticket..
