I heroic reincarnated to add some ability points. And since I hit 20 (it's now 24) I've taken almost all the Valor each time. Always doing EH. And I banked about 350. The problem is that lower Epic quests gives piddly amounts, even at or under level. It should give the SAME amount as upper end ones. When I'm 20 and doing a level 22 quest it should give the same as when I'm 28 doing a 25 or 26.
I don't mind if there's a diminishing return if I'm 28 doing a level 22 - that should only give 10 or so, but 12 at EH when I'm one level under quest? It's idiotic - that's what. Just like with off destiny leveling this new valor grind is mind numbing. It's boring since the only rewarding quests are the most boring ones, like the harper, wheloon and stormhorns. They're dreadful. Plus the scaling is off so it's difficult to do EH on those quests (solo) since everything saves anything.
To put it simply; the design is that most of the 'grinding' will be done in upper end quests and that's terrible since those quests are horrid compared to the wealth of quests below it. By creating such a disparity between the lower epic and upper epic, where it's unrewarding to play anything other then the harper and above, you get in this late run funk where all the fun grinds to a halt. Up until 25, before you start touching all that stuff it's okay - then it gets bad and quickly.
Worst of all, multiple ETRs don't reset slayer counts and everything else. So eventually a lot of the additional XP you rely on dries up. And you end up grinding the same quests multiple times for not only XP but also piddly amount of Valor.
And if you're doing that for Karma in a off destiny, well good luck to your sanity.
I just don't see this system being sustainable in the long run. You can feel the grind and it's painful. 3 terrible system baked into one; valor grinding, karma grinding and off destiny leveling.
