New to MRD..have some questions.

BLM is by far the most used DD job, however, MNK and DRG shine in certain situations.

For exp groups THM is extremely overpowered as they can frontload a ton of damage, while for a melee it takes time to get the DPS roling and by then the enemies are dead. Exp tanks only shine when you do large pulls of enemies that significantly outlevel your group, in which case the casters cannot wipe them out fast enough so you're actually needed to keep them off the squishies. You really need the GLA hate abilities to pull this off, however, and from my experience most people cannot competently tank more than one or two mobs regardless.

As a relatively new player how exactly does a level 30-something MRD/WAR tank groups of mobs when THMs and DDs start AOEing and attacking random mobs right away? I know when I have 4 mobs keeping them all in control really is quite difficult with the abilities that I have at my disposal.

You can Provoke one mob, Flash another and combo a third. GLA does a bit better because Rampart and Shield Bash are great for holding even a fourth mob. If you have multiple THMs each focusing on a separate mob, though, sometimes there is just nothing you can do.
