I think number 3 is correct only before you pull anything. If you have pulled and you want the others to stay behind your back, some enemies will cleave and kill them. I remind others when that happens, especially healers because they really want to stick with you, body-to-body if possible. So I guess you could say, others should follow behind you before pulling.
Otherwise, I think they're all correct.
OP: Please don't blame the system without proving a valid point, without comparing it to other systems. FF14's battle system is not faulty but it just leaves so much else to be desired. If you like the other system better, that means you have an opinion and a suggestion to change an aspect of the system to your liking. You can make a suggestion, no problem, but to just blatantly blame the system in itself as faulty just because you can't tank as a DPS? You're playing the game wrong, mate.
