I don't see how you could possibly dislike the random encounters so much and still enjoy the games.

Another crucial reason is because with random encounters you don't have to design the zones around being able to be fightable in. This is one of the reasons I found FFXII's zones to be very boring (design wise). As for skipping enemies, if the game fighting style is so uninteresting that you want to skip the majority of them, then I think the flaw lies in the battle system itself.
