I solo-ed P1 with Teebo+EE+CC+QGJ+Phasma. All f2p toons now. I stopped working on ES - always had fun using Chirpa and it worked out. But ES needs a scanner at gear X and is only at 60% potency. Chirpa doesn´t have to be gear X like Scout. It´s all about him or Phasma speeding up your toons at the right time. Someone here in the Forums even used a level 63 Chirpa to solo P1. @LordStyling of course you want a maxed out teebo/phasma for soloing P1. I gave CC (gear IX) an omega for his basic (+15% dmg). My QGJ is maxed out, but omega on his basic is needed for sure. And Humbling Blow makes sense (3 rounds offense up). EE has omega on basic only. Phasma definetely needs both specials on omega.
Edit: one of us also solo-ed P1 with GS instead of CC. Works, too
