TP matters as far as making Resta full heal at LV10, above that, naw. If you wanna be vey practical, you shouldn't use Techs.

The difference in attack power between Humans and Newmans is very practical, I'd suggest ONLY choosing Newman if you like the idea of having a high EVP. When it comes to the later parts of the game, Humans will end up completing Story Mode Open Missions much faster than a Newman, but apparently Newmans are much safer in some Multi Mode Tactical Missions.

Dark Mirage Blast is fun... It's not a strength.
