Can we know the point of view about Mr. Pinchy of WCL?

At the end of P2, there are several speed-run guilds trying to use the Mr. Pinchy to provide an extra sunder-armor debuff to bosses, which may become a common used part for all speed-run guilds in P3.

Want to know the point of view about this from WCL side, it’s good to have it in outdoor, but don’t really like it when using in raid.
