Concerns about " Getting rid of unused and ineffective actions"

[Zojha]

What i'd like to see is more encounters where these skills are actually needed [...]

But that is just making things artificially useful via content design. In a similar vein, you could make Cover and Healer LB3 (more) useful by making a mechanic that kills all targets except the Paladin and his covered target - after everyone but the two are killed, the LB bar instantly fills fully. Obvious solution to the fight: Cover the healer and healer LB3 afterwards. Suddenly, cover and healer LB3 become extremely useful, mandatory even! But that's entirely artificial.

You mean like with Bahamut an Alexander and the Tank LB?
