We really need a way to make use of DarkSide as a ressource. The ressource management of DRK was always the fun part.
If we had to be careful about having enough manage to use edge/flood to prolong DarkSide all the while spending it as much as possible on some skills (dark art enhancements or others) it'd be great I think.
I mean, maybe Living Shadow should cost DarkSide instead of Blood (even makes more sense lorewise). So we'd basically have to try and keep darkside between 31 and 60s when Living Shadow comes off CD, takes 30s out of it, etc etc. Meaning we'd have to keep enough mana saved for it, between spending other abilities.
