Ghostcrawler thinks the idea of a cooldown has "potential long term benefits" with the likelihood of a significant backlash from the community. I would agree. But perhaps Ghostcrawler was simply touching on a type of design change that would reduce the playerbase to a bunch of screaming, crying, thrashing babies.
Fast forward five days and Bashiok weighs in on a thread centered on the debate by quoting a forum poster who offered three simple words: "Not this again."
What say you? I may formulate some thoughts and revisit the topic at a later date. Or I might be too busy flying from zone to zone collecting missing battle pets. Oh well.
