I was doing veteran Bloodrot Forge last night when the healer admitted that he wasn't a real healer and that we were going to have to slot a self-heal. As I was on my magplar, I would have loved to swap out my DoT morph of Ritual of Retribution for the HoT morph, Extended Ritual. It feels really strange that since none of the other 4 skills had been bought, I could literally add any healing skill to my bar except for the one I really needed.
Likewise, there have been times when I've been on my warden when I've liked to swap out Subterranean Assualt for Deep Fissure to make up for a lack of tank in the group. Ditto on my sorc with swapping the Twilight Tormentor for the Twilight Matriarch when I need more heals.
We have a literal armory system that allows us to change between completely different attributes, skills, and equipment setups (as well as Vamp and Werewolf) but we can't swap out a single morph when we really need it. We are also in a strange situation where with each new chapter and dungeon, the number of skill points available increases but the number of skills we buy have not changed in Greymoor.
So my suggestion is why not allow us to select and spend 2 skill points getting both morphs of a skill e.g. For Vigor, we can get both Echoing Vigor and Resolving Vigor. It would be easy to make it so that we couldn't have both morphs in our skill bar to prevent builds becoming OP.
This would be a massive quality of life improvement.
