Destructive Touch and its morphs are really lackluster. Combining a direct damage and a dot in one skill that's not quite a good dot and also not quite a good spammable renders a skill useless. I don't recall if it was this recent update or the Markarth update that changed this skill as I've just had force shock slotted for the past few months, but I've been leveling up a new character and taking a look over all the skills again and noticed how garbage Destructive Touch (particularly the Destructive Reach morph)[1] has become.
My suggestion for this skill is to consolidate its damage with other spammables as there's already a plethora of good dots, and adding another isn't necessary. There's only 2 spammables for staff users, and that's Force Shock and Elemental Weapon. Adding a third whose appearance is the element of your staff adds a roleplay element (wanting to use purely elemental damage, cryomancer, pyromancer, etc.) as well as adding another spammable option to slot.
Making this change will make the Destructive Impact set worth something again, since it got reworked and was actually a good alternative to a monster helm, and then a few months later was yet again useless because the skill it's dependent on was turned into hot garbage.
Fingers crossed the relevant people see this because I would love to have this rework and it needs to happen, otherwise, there's just yet another useless skill that isn't good for any build or playstyle except maybe casual fans who only do overland content and can get away with using bad skills (not knocking those people, that's still a valid way to play).
