My list of changes
- Defense matrix uptime increased to 3 seconds from 2 seconds
- Fusion Cannons movement speed penalty reduced to -25% penalty from -50% penalty
- Fusion Cannons weapon damage per pellet increased to 1-3 from 0.6-2
- Boosters cooldown reduced to 4 seconds from 5 seconds
- Boosters duration increased to 3 seconds from 2 seconds
- Mech health changed to 300 health 300 armor from 400 health 200 armor
I think with all these she would be viable again but not a must pick or meta. She would be more mobile and regain some of her tanking ability with a very slight damage boost.
