So I take it every other class is trash because they don't have VF....it's a crutch. Sure, allow the nades to do a higher damage, but DoT has no place in the normal (no super being used) combat. But I respect your opinion.

Sunsinger neutral game relies on VK firebolts time and flame shield. Flame shield is already getting a huge nerf. If you remove VK firebolts or nerf them too heavily I don't think anyone would use sunsinger in pvp anymore. Right now nightstalkers and strikers are the strongest classes.

Sunsinger has 2 other grenades. Fusion grenades are fine, other one (idr name) could use a buff to AoE and damage it causes. I would say lesser skilled users rely on viking funeral time, not sunsingers as a whole. I think flame shield was fine, except in pvp, where the overshield should apply on kill, not hit. They reduced the amount of overshield it gave you, so I don't think it is that big of a nerf. However, we will see once we actually spend some time playing the update.
