Lich ascendancy "Dominion over flesh" curse duration small node change proposal

The ascendancy for "dominion over flesh" of the lich is based on doing things with curses.

The second small node just before dominion over flesh gives "Increased curse duration by 25%". However, as of right now hexblast requires half the curse to have expired.

It really counters the idea of reducing effect duration, by a lot, and using hexblast, yet its a very important node to ensure enemies immune to hexes don't ruin a particular build. I propose a change either to curse area or curse magnitude increases for the small node, which are always positives, the first small node already does that for this ascendancy line.
