I think I understand what he's getting at. The "phasing out" seen in TOS seemed quick and painless (just like a flash of light) while the process in ST II seemed painful and crude.
Now, am I the only one who thought Lt. Galloway's death in "The Omega Glory" was totally nnecessary and - from Captain Tracey's point of view - one of the most stupid decisions in his career as starship captain? (or the screenplay writer?)
The idiot was in desperate need of fresh phasers, yet he didn't stun Galloway but "phased" him out - and the fresh phaser
Galloway had been drawing along with it...not to mention it hardly looked as if Galloway would have actually been able to use his phaser on Tracey.
