Scripted fights.

[Firon]

snip

Non scripted fights are not super hard but it makes the fights not stale, so with this mobs can use what ever they want and still have a set of rules, You can go watch 10 1.0 garuda fights and she will never do the same thing in every vid except do AB when she is @ 40% hp or below.

Like darnus hard mode in 1.0 when BG beat that ppl could not just jump and replicate that fight cause the fight will never be the same for you. In 1.0 If ifrit wanted to he would do eruptions 5 times in a row and u couldn't stun it!
