Skill based fights..

[Mardel]

FFXI boss attacks were random , u couldnt predict the next move , thats why we had Stun rotations , and kiting in some encounters , aoes on FFXI killed whole alliances (stonega IV >>>>> BOOOM!) , and thats why /nin become a popular sub for melee DD jobs (and even ranged)

FFXIV u know whats going to happen Next and after that skill boss is doing X and Y Z /loop , boring as hell

Those may have been "random" but they out of a pool of specific skills though, thus the randomness could narrowed down. FF14 just doesn't have the sheer amount of abilities to compensate for a "random" attack based boss. Certain mechanics in this game would just make fights sheer RNG.

Also ff11 could afford to make fights in sky/sea a bit less scripted because of alliances having people on the sidelines. Thus eliminating a lot of the threat from someone dying.
