I had a major problem with this today. Logged on for my lunch break and saw someone shouting a Hunt. I was on WAR at the time soloing and ran over. I normally go BRD but I was worried it would be dead before the cooldown wore off. I get there and there's no tank and I get asked to tank. "No problem," I think. The thing will be dead in :05 anyway.

Nope. I had no idea they'd buffed the HP (hadn't read the patch notes yet). I Tomahawk and people started spamming skills and I completely lose the mob. Can't see anything. Massive lag. Someone's yelling at me to Overpower, and I'm thinking, "Yeah, sure, where?" All my skills are red as if the mob isn't in range. It finally pops on my screen and a DRG is kiting it. I manage to get hate and keep it, but that was some seriously godawful lag.

From now on I'll just go SMN or BRD. At least now I know I don't have to worry about the cooldown.
