Mogtalk interview with yoshi p

[Risvertasashi]

The problem there is that healing creep just makes people ignore the vulnerability debuffs. Now if the debuffs were always negative (eg burrs from Aurum Vale) as they stack and didn't time out, then perhaps we would see a mechanic that has a damage curve that is exponential that leads into a wipe if the healer doesn't remove the debuffs.

I would have to disagree. They've been ignoring them since... as you point out, AV even.

I still think the root problem with vuln stacks isn't healing power creep. It's that it punishes the healer for a non-healing mistake. People don't really care about how much healing they require. But hurt their DPS, they care about that. It gives feedback between failing a mechanic and the consequences, which vuln stacks don't really do.

My 2 gil anyways.
