merge wither with blight spell please

Hit spells can easily use wither on hit to apply wither very quickly instead of channelling. which is why i feel like seperate wither skill doesn't seem necessary. totems exists, but its way better to use wither support or any other option.

using wither with totem and casting blight myself is an option but, I would rather avoid totems. wither shouldn't require totems when other playstyles can use it much more freely.

which is why I would suggest merging wither spell with blight spell. they are both channel skills, both have short duration which requires continuous channelling and blight isn't a hit spell which is why it cannot take advantage of "wither enemies on hit" mods/passives, and I basically have zero source to apply wither if i use blight currently. except occultist's "withering presence" which takes 15 sec to reach full stack.
