Don't you think these mods should work with elemental wells that match your weapon type and not subclass type? I think this change would give us more build crafting possibilities (yes, I know there are other ways to create the exact type of well you want but what if)
For example I'd like to use middle tree Arcstrider in some harder content, but it has no healing capabilities, so I'd use a solar primary to create solar wells and activate Well Of Life, plus bonus damage to my sollar weapons
Or bonk hammer Titan, where I'd use an arc primary to create arc wells and activate Well Of Ions plus boost my arc weapon damage
I know these aren't the best examples but you see what I mean
