Any updates? We haven't heard anything in over a month. I think I speak for everyone (almost) when I say we appreciate you a) communicating with the player base as you did with this thread and b) seeking our feedback on this very important change. With that in mind, and also keeping in mind that you've said this is still early stages and nothing decided, a monthly (or so) update would be nice to calm the masses. Just something brief like "we are still working on this and have yet to make any decisions (except that we won't summarily remove ED XP)". Or some such.
Personally I'm hoping for for a choice of 2 types of epic TR:
1) TR to level 1, lose all XP in the active ED only (it must be capped to do this), get benefits of both epic and heroic TR
2) TR to level 20, lose all XP in active sphere, gain a epic (ED) PL ability
Either way leave the option to heroic TR instead.
For ED PL benefits I'm thinking something like....
Gain 2 pts in tree (usable at tier 6), gain 1 fate pt
Epic completionist: gain 2 fate points and 1 twist
Most of the recommendations I've seen for PL benefits would be game-breaking broken, so I'm trying to keep it reasonable but worth doing (for most, not everyone uses the existing TR system either).
