I'm thinking a loco FF-troller might herd to capitalise on his AoE hold but for a loco FF-mm to herd... her minions will probably get distracted out of supremacy range. However, assuming they stay by her side throughout the herding, the only benefit I see from this is for a Corruptor to then nuke 'em or a Dominator on the team. Maybe I dont understand because I just solo or team with the Gang.
At any rate, with Scorpion Shield and Dispersion Force Field running you're looking at just under 30% defense to lethal, smashing and energy. Top that with other available self defense buffs such as Combat Jumping (+3.9) and bodyguard mode, maybe even Force Bubble to prevent the melee attacks and sustain aggro, and you've always got Personal Force Field if the dust hits the fan. Its do-able without Provoke but I can imagine it'll help keep aggro.
Why you would want to herd with a MM, usually quicker to see and kill?
The mercs have fairly good AoEs at later levels, and zombie vomit is a fairly large cone. Both benefit from tightly packed groups

mercs and fairly good aoe? lol not really 
More like annoying cones wich they serious dont know how to use, only once in a 100000 times you get great use of their cone fullauto's.
Easier to farm for that, using corners etc and drop a -slow power at the corner.

Hi all
I have read US guides on the viability of herding sucessfully with a /ff troller. Surely the same tactics can be applied to a /ff mm in bodyguard and especially post 40 with access to patron powers. Wondering if anyone has tried this with success or seen a guide to it. Would you have to get the taunt pool powers in order to do it well?
Interested in your comments and ideas.
Thanks DD
