Just do away with the caps, everyone hates them and they create major problems for players with multiple actively played alts. I understand (from the company's point of view) the need to have a cap on embers, but motes and local region tokens, what for? Festival tokens, what for - to stop playing the festival? And now currency to build the LI, capped?
(listen to your playerbase, please)
Bridles, that's probably a reason for the old LI panel to stay and the "transition period" to extend forever, which will benefit those who took a long break from the game
Now, mithril coins.
Even if one level of advancement will require one MC, it will be 49 MC per tracery, and it will be lost after you replace it with a better version (or higher level version, on level cap increase)?
NOTHING paid with real money should EVER be lost through the normal gameplay process. Overwriting a tracery looks like a normal, intended process (and as we had gear levels increase, probably there suddenly will be better traceries from a new raid at some point... probably with the same % to skill but with better secondary stat, the one which benefits from enhancement runes). It's obvious - if you got lucky, you'll want to replace the existing one. But if the progress is lost, then 1) You'll think twice about slotting it and therefore might have no incentive to run the new raid (and pay for content), and 2) someone would slot it, expecting the progress will be kept, lose all spent MC and start writing tickets, only to be answered "Working as intended". Customer unhappy, sub cancelled. Probably.
I'm not sure I would even chase (free) enhancement runes if there's always a better version of any tracery. Get one and sell on AH
As for leveling... it is a big improvement that reforging a LI will increase its DPS, but those level-locked traceries would probably make me just forget about them, unless they drop from mobs. I mean, farming all Middle-Earth factions to barter for a skill, if in 5 levels it won't be usable? I'll pass.
