She's... okay. She's fast, and can hit pretty hard, but her damage is contingent on building up heat over time, so is not really front loaded (not ideal to quickly burn down your enemies). Kinda like a... reverse Ares. She could be a pretty decent filler for a team, just not particularly "good" since she doesn't really make the team better like svarog/amon, nor can she compete directly against Uriel. Still, she can work if you have some good sustain on your fire team, unfortunately, that really just means summer Sol and a good beefy grid.
