I actually tend to agree with this, which is why I do my solo stuff without temps or incarnates of any kind (not even alpha slot). So far, I have soloed all GMs including Lusca and Kronos Titan, most AVs in Maria Jenkins' arc (damn Malaise with non-positional attacks and Dominatrix with 50% res to all + spamming ranged holds), all AVs in Mender Silos' arc (on both sides), on my Blaster (Beam/Mental), Defender (Therm/Ice), Corruptor (Fire/Rad), Controller (Fire/Cold), and Dom (Dark/Psi). My MM (Thugs/Traps) is also a solo beast, but cannot take down Lusca due to her mechanics being pet unfriendly
