After spending countless years tweaking, nerfing, adjusting, nerfing, giving nothing to drk and pup and then some random buffs to make sam more BA and increasing the effectiveness of certain classes that were once hated (DRG) the game seemed to go back to step one with ABY. I dont have "fat lewt" and "AF3+2", in fact im "lolpinkblugearwithnoalmacefail" but it doesnt take all that to realize the major flaws of aby. Aby brought many good things to FFXI: the most important being incremental progressions vs camping nms for 3 days. However, they couldnt of been any more wrong with the proccing system.
Currently the trend is your either NIN,WHM,BLM,MNK, or WAR or GTFO. Now this isnt the staple for everyone since you only need this well rounded setup when low manning. Low manning requires a little more skill and dedication for a larger payoff (less ppl = less loot shared = AF3/Trials done much faster = profit) but requires most if not all these classes to hit most procs effectively. So what happens if your not already one of these classes? LolrollWHM.
What never ceases to amaze me is that SE had a proccing system right under their nose, its what we call a "Skillchain" Make more skillchains and require corresponding elment skillchains/bursts in order to trigger weakness = more combinations of classes = INNOVATION! that and not shunning the other 13 or so jobs in the game. The other thing is doing away with atmas when bringing out the level 99 content. To those of you that disagree, i understand your thoughts but the better characteristics of each class and roles are much better rectified without them (Any decent EVA class becoming a EVA tank with the right atmas e.t.c. e.t.c.).
TLDR:
1. Replace the proccing system with a interactive and expansive overhall the the already included Skill Chain system in the game giving the other 13 classes that dont include WHM MNK WAR NIN BLM more use and abolishing the possibly stagnant bandwagon classes to others that wouldnt enjoy playing them.
2. Do away with ATMA or add the new endgame outside of abyssea.
