Yeah I'm drawing a blank on what would have enough holds for the post-buff mitos, ranged and melee dps, enough debuffs for the AVs plus be able to shrug off the endurance drains.
Yeah, after a few attempts I had to tap into my other accounts for some alts thus having a team of 4 and used 4 fillers to launch the thing.
They would sit in the RWZ base as my main would do mission 1, 2 and 3.
Then I would bring all my alts into mission 4. The main would work on getting the Rikti to attack the Hami this wiping them out and possibly taking some of the mitos out at times.
The main would then work on the yellows as he was my inv/ss "superman" tank, my ranged alt would deal with the blues, the debufferholder would start in on the greens so that my main could swoop in and take them out while using an EoE and making sure that if the Hami attacked that he would take the hits. Alts that were not in use would either wait at the mission door or behind rocks out of site of the hami.
Then when it was time to take down the hami, the tank would pop EoE and set taunt to Auto and the other alts would blast it to pieces.
After that, mission 5 was generally done with just my inv/ss superman tank that also had incarnate pets and shivans so the alts would generally door sit until I cleared the area for the last fight then bring them to the area (alt #4 was a forcefield MM and all alts were defense capped)
So my "superman" would finish the LGTF, all alts get rewards, and strictly speaking I still soloed it.
