I understand that, in fact I hate high encounter rates too. Its just in my case, my old habit is always kicking in whenever I play a JRPG, running away or avoiding fights is something I never liked because I lose exp, money and possibly lose the chance for some sort of rare item drop. Im just paranoid that way. Heck, in Pokemon, I never actively used Repels until Heart Gold/Soul Silver remakes! And sometimes, when the battle system is fun, I don't want to run away at all.
My policy is that if I'm starting to get tired of encounters I avoid them. I can always grind for EXP/money and rarely items later. I usually don't have to though.
