Tying karma to specific spheres is silly. If off destiny leveling now is a terrible mindnumbing process, then imagine doing so for tree times the amount of XP (roughly 2 mill to cap a destiny right?).
I just don't understand why karma has to be tied to a specific sphere. Shouldn't it just be a matter of hitting 6 million points (that is 6 mill xp)? I mean the only thing you need to heroic reincarnate is to hit level 20 and have the heart of wood. Done. Plus you always level in a enhancement that is in perfect synergy with your class.
With off destiny karma leveling in a sphere you're completely out of sync with your class, for 6 million points. So if you try to level off destines at the same time as you gain karma you will effectively prolong the entire process. And since you can only gain valor (so far) by completing sagas it's highly ineffective to try to gain karma in anything BUT the saga quests. Even if you find other quests that are better to level in (like von3)
This is just awful design. Worse then regular off destiny leveling.
Turbine cannot have created a worse incentive for anyone to want to ER more then a few times and there's no real point even contemplation something like a 'completionist' or unlocking all extra fate points (1 for every 4 ER).
This is fail from the beginning.
Untie fate points from destinies to allow people to level as they like. Put it on it's own XP track.
Untie Karma from spheres. 6 million points is 6 million points. If it only takes 6 mill point to ER, then why should it matter if it's done in A sphere or B sphere?
