Well, I've come aways since my last post. Thank you very much to everyone for the helpful advice. Thanks Hachoo for your videos, I have found them to be extremely helpful.

I've cleared Heroic UK, but Prince Keleseth is always a tough fight. Frost Tombs just seem to rock my world. I have read about putting a "/target Frost Tomb" line in my DPS macro, but haven't seen any actual macro, so I'm curious to know if anyone has tried this. RIght now, I do have a target Frost Tomb macro for my DK and then the shaman assist him to nuke it down.

But, perhaps this would be an improvement. Or would it not work?

/target Frost Tomb
/cast Lightning bolt
/cast [target=focustarget] Lightning Bolt

Watching Hachoo's videos, it just seems like he blows Prince Keleseth apart real fast, or perhaps the magma totems take it out. My fights go on a bit longer, and it seems like Prince Keleseth likes to put a Frost Tomb on the same target twice in quick succession. Perhaps that is just my bad luck.

Anyway, I've been able to kill this boss, but I'm interested in making the outcome a bit more predictable.
