New to MRD..have some questions.

[Frein]

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.
