Well I'm only level 35, so I've never seen it in action. I know its better, but we can't have the exact same spell with a bubble effect. It'd be a cheap way to go.

I posted this in another thread, but it works well here:

In situations where everybodys HP is dropping super fast from unavoidable AoE, there isn't much I can do. Everybody is constantly losing HP, but I can't just cast Adloquium on the tank to heal the dps, since he's taking that AoE plus the damage of the boss/adds. So I have to focus on my healing, and hope my fairy heals the dps, until a point where the tank is fairly stabilized and I can spare 2.3s to cast and another 2.5s gcd.

It feels almost 100% useless to use Succor in these situations. It heals for me around 150 HP, and with the constant damage the bubble is eaten instantly. I'd have to spam succor around 8 times to fully heal everybody from them being around 40-60% health. I know that's not its use, and I would be instantly OOM if I did that of course, but the crazy low potency bubble on it makes it feel pointless to cast for a bubble, and same for the heals. I feel like Succor really has no place on my action bar. I don't know if it changes later, but that's how it feels to me right now.

Maybe it would be better if it was made into an AoE 250 potency Bubble. I feel like it needs to specialize. Maybe if it was a pure bubble, it would be good to cast BEFORE an AoE to prevent the damage, as opposed to trying to work with a measly cure and bubble effect that don't really do much of anything together.
