We had a very high dps team to drop Simin immediately after she came out of stealth. Mesmer with bubble, thief to keep the healing to a min b4 stealth, 2 dmg eles, and a war. We got the sparks back into place before she returned back to 70%. We all were spec’d right and all had pure damaging utilities. Still we would gain 0 progress.
The sparks were not the problem, it was that no matter how high the dps, she would still go invulnerable and invisible at 50% and heal back up.
