i have an ill/bubbler and i confuse some of the mobs near the scientist then throw phantom army and phantasm (all while in superior invis). after they are all dead i throw up personal force field and dispersion bub and take a care free walk to the destination and repeat 2 more times. Then i just leave def toggles up and do the last 2 (click computers)

. When someone comes to attack me i just ignore them and keep moving. Bubblers FTW!!!
