Thanks TBO, I did not know that. The other reason I like A though is because it is close to the 1, 2, 3 and 4 key which was nice, but if they make it another key that is in that vicinity, that would be ok to I suppose.
My finger is also really used to hitting A thanks to starcraft/warcraft and other RTS game, so now I sometimes move the screen and stop following my demigod by mistakingly hitting A. Then I have to go find the T key in order to re-target my Demigod.
