NOPE. He would never feel 'not himself' in someone else's body personally, because he's always pretty centered in who he is no matter what form he takes/shape he gets shunted to. But that would be the only part that didn't feel wrong! Knowing someone else has to deal with his Exsphere problem and manasense is awful. Having someone uninvolved learn about the Exsphere problem by experiencing it firsthand is awful. Potentially seeing someone get the screaming jeebies over parts of who he is is awful. He would still be getting a lot of horrible pings despite being physically disconnected from the prompters but be obliged to stick it out and stay with the unfortunate recipient of his body to coach them through it.

Bodyswitching could also wind up pinging off memory things like shoving Martel into Colette and trying to possess Lloyd and possessing Colette/dying/failing to keep a grip on her, so he'll just be less and less okay with it as time passes.

Lloyd's ideal vacation spot!
