Am I wrong in thinking that the difference between full AF+1, Full Allagan, and everything in between is only a trivial difference? All the gear has identical strength/vitality, our primary stats. The only thing is that you should either be close or have accuracy cap. Everything else is minutia.

Can someone honestly say that one i85 tank is SIGNIFICANTLY better than another i85 tank in a completley different mixed and matchd gear set?

My philosphy has been, if it's an upgrade.. roll on it. Is there any reason for my to save 825 myth tomes for Warrior AF+1 Chest if I already have allagan chest piece, just because most if not all BiS lists have AF as a better BiS than allagan?

I think that there are a million things that could cause you to wipe in turn 4 or 5, and not having BiS is not one of them.

My personal opinion is, go for BiS if you're ONLY focusing on a single class and you ahve the time to farm it. If your'e like me, who want to have 2-3 i80+ jobs, you take the upgrade knowing full well that BiS gives you a marginal advantage where it will never make or break a given encounter.

My 2 cents.
