I have a
5* & 4* Tech Awakening Gem
I'm seriously considering awakening IMIW and use on war defense since my team could use a boost.
5* on the other hand not so good:

I'll likely save my 5* gem.
Note: Tech Champs I have maxed: 4* Green Goblin & 4* Vision (both awakened) // I have no good 5* ranked
So should I save these or use them? Or use one?
