If all that is as serious as you say, then explain to me why noone spends any effort making medicines to combat those things, or bothers using materia that bolsters the defense against the very things your saying. I am not claiming these things NEVER happen, I am stating that they happen so infrequently there is no reason to plan ahead of time for them. When is the last time you used an antidote or thought about beefing your boots up with chocobo down materia? The fact is, you haven't, because there is no reason too.
No where in my post did I say these things don't exist in the game, only that they are used so sparsly and with such little effect, most of the player base doesn't go into the field concerned with what will happen if they get paralyzed in a fight or poisoned when out on there on own.
First, you don't need to give me the gist of what I am saying, I know what I said. Second, you make a HUGE amount of assumptions about how I play the game without knowing a single thing about me. Third, for the purpose of my post, pretend I was only talking about mobs you would solo or party against for xp. When I said "obviously higher mobs" in my op i was referring to things 12 levels or higher that no one person or party would have any business messing with. I am well aware that DC mobs aren't an issue, so lets put this another way:
Say your party pulls a group of beastmen that contain the jobs of archer, conj, and warrior. Now ideally the archer would use bind effects on top of its normal damage output, thereby mucking up either the tank or one of the healers in your party, the conj would cast cure spells to keep its party members alive longer, and the warrior would dive right into AOE DD's that would hit more than just the party's tank. The fact is all of these things DO happen already, however they aren't done in any way that really actually hinders your party for more than a few seconds. The conj mob ussually only cures itself, the bind effect caused by archers lasts for all of about 10 seconds, and (most of the time) war style mobs only use single target DD skills. These things are in the game, but not at any level that requires any sort of tactic besides spam AOE move, and wait out DOT effects for 10 seconds. Not challenging. Not stimulating. And after a few dozen times, not really all that fun.
