Unleashed is min-level to save forma because I can't think of a time you would need the extra range and the wiki says it only works on capture targets (I haven't confirmed this). If it does only work on capture targets, both why are you using this kubrow instead of another and go ahead and replace the mod. I have given this build shields to take advantage of the Mecha set's extra shield [Regen]; don't take it against infested and make sure you have a method of healing your kubrow unless you add a health recovery mod in place of [Unleashed].
