The Nightblade's Dark Shades skill, the one that summons two melee shades to fight by your side, can be a bit tedious/annoying when having to constantly recast the ability to keep it up between battles (especially since you have to target enemies to cast it). As it currently plays, Dark Shades isn't as fun as Shadow Image and it feels more like a chore than a fun ability to use.
What does everyone think about the possibility of making the Dark Shades morph a toggle? Hopefully it would make the skill more fun and less tedious to use.
Making one morph a toggle while the other has a timer seems to work well with Leeching Strikes/Siphoning Attacks, and the same success could be replicated with Dark Shades/Summon Shade. Summon Shade would be too powerful as a toggle, but with Dark Shades it could work wonderfully.
Note: I am presenting this idea based solely on my experience while using the Shade abilities in PVE. I have never tried them in PVP.
