It is literally impossible to counter a Well of Radiance Super without a big AoE damage super or a Golden Gun. It takes way too long to destroy the sword placed in the ground (if you even manage the god-wonder to fight off the aim assistance dragging you off onto players). Players inside it have ridicules healing and overshield regen (which is fair since it is a super), but the fact the Super is ALSO insanely hard to shut down, makes it more broken than any other super ever was in the past in pvp. When a Bubble Titan dies inside or outside the bubble, the bubble goes away. You can still be debuffed and killed inside your bubble pretty easily unless you run a shotgun or are not alone in there. It prevents bullets to go in and out, making it basically a shell. Meanwhile with a Well of Radiance, 1-6 players can have a super easy time shooting at people while being basically invulnerable due to high healing and overshield unless they have a super. Considering that Well of Radiance is ALSO Tier 5 super and recharges fast AF, especially with Phoenix Protocol, it is very often usable and also very, very effective compared to other super abilities. The only Solution that doesn't nerf the Solar subclass or makes it unfair for any other class is to let enemy Suppression grenades affect the Solar Sword for a reduced duration (duration on Players is 10s, Sword should be affected only for 5s). That way Void subclasses become more important in PvP, Well of Radiance isn't nerfed in PvP and it still requires a bit of skill or timing to have a grenade ready to ruin that Warlocks day.
