Skipping mobs is a huge time saver. There are alot of mobs in MC that can be skipped if your raid is careful. I’ll point out a few, here, but the best thing to do is have your hunter/puller try them all himself. He may need a few resses here and there at the beginning, and you may want to spot him some gold for repairs, but having that information drilled into his head (here’s an MC map for reference) is much more valuable than reading it on here.

Only one group of imps in the imp caves need to be killed —  the ones on the right side before Lucifron’s room.

Several of the mobs in the first room can be skipped, particularly if you’re coming back into MC after having killed Magmadar and Garr already and have no worries about patrols chaining them.

Most of the mobs around Gehennas can be skipped. (some will need to be cleared on the way back to get Ragnaros if you don’t get them now) Just clear along the wall, then pull him. Note that he’s a fair amount harder this way because he targets his AoE more effectively when people are bunched together in this more narrow location. You can do it.

Some of the stuff between Gehennas and Garr can be skipped. You could probably, if you felt daring, even skip clearing Garr’s room except for the pats. Depends on how comfortable you are with fighting Baron and Shazzrah. I like having Garr’s big open room for those two, so we clear it.  If you’re just clearing to Garr and stopping for the night, I probably wouldn’t bother clearing his room completely.

We typicaly clear out garr’s room, then clear all the trash before Geddon and Shazzrah, and then kill Garr/Geddon/Shazzrah all in a row. I’m not sure how much time that actually saves, but it helps the raid keep its focus, you’re not changing from trash mode to boss mode and back.

All the stuff by Shaz can be skipped, most guilds that fight him in Garr’s room do this by default already.

You can probably skip the trash on the right side of Sulf’s room, and if you do the “aoe the priests” strategy, you probably should. We havent tried that one yet, so we just kill ‘em all and spread them out nice and far apart.

You can skip all the lava packs in golemagg’s room. Just kill the stuff along the near wall, and pull him to the entrance to his room. One plus to this is that if things get ugly for some reason, you can actually reset him like a ZG boss by having everyone back up the ramp a bit. You can also pull Golemagg from the bridge behind him, if you’re willing to deal with all his adds at once as well. I don’t think you save any time this way; you’re killing the same mobs… but I have to admit it’s pretty darn cool watching Golemagg charge through his room and up and around to come and get you on that narrow little bridge.

Of course, as I noted in the Overview, this is for experienced guilds who’ve been doing MC forever and don’t really need the extra money drops from MC can bring to the guild bank or the extra fire resist gear mats.

So there you go. You have the basis for making your Molten Core runs take less time. Have fun!
