Meta: Removing it from morphed unit

I'm trying to use Meta to change classes on units in my game. But when my unit's meta the metamorphisis stays on the unit. Is there a better way to do this (the new unit has to be able to use new abilities)?

The only areas I want to change on the unit are abilities dmg and hp (Not attributes or any stats). Or is there a way to use bear form and remove the ability to turn it off?

If you know a better way or anyway at all plz help.

Back in 1.13 or so when the editor was bugged to hell I tried to make a hero called shapeshifter who used 3 types of metamorph spells. It was buggy as hell but that might have just been the editor. What you have to do is remove the ability with action - unit - remove ability. If he's going to change back you need some variables to store which abilities he has and which levels they are. Then we he turns back give him as many skill points as needed and trigger him to spend them all on the abilities he had previously. Hope it works for you.

I already tried removing the ability via triggers. I'm thinking I might have to make the abilities activate via triggers.
