For the next expansion: skill trees and/or more varied gearset options.

[Daemic]

People like to feel their character is unique, and the ability to create your own build using abilities from various skill trees for each class fulfills that desire. With skill trees and proper balancing it is entirely possible for there to be a great number of valid builds for each class.

Every player knowing they are a carbon copy of others of the same class saps enthusiasm and causes a skillful playerbase to stagnate, leading to players doing just enough to not get kicked from parties. With builds, players have a creative outlet and a reason to contribute 100% in raids/dungeons/etc. by demonstrating what their personal build can do.

Gear sets: I'll keep this really short and simple: more than one endgame set of gear. The current model of "the highest iLevel is the best" needs to be re-examined.

There will be one build superior to the others and this will become mandatory. Anyone not using this build will be treated badly by some and it will create more division in the player base.
Devs will have an even harder time balancing and eventually just give up; leaving a clear and zero-choice route to the optimal build.
This is just the way of it in class-based MMOs.

While you aren't wrong, there is room for it within FF14 using the Role abilities.

For example, they could add more defensive CDs and oGCD attacks for MT and OT. Healers could spec between buffs, regen or shield mitigation depending on playstyle and party comp. DPS could spec between solo buffs, party buffs or extra oGCD attacks.

Depending on if you're soloing or what kind of group content you're doing there would be a different set of skills you'd want.

If I have to change the skill set for every contents, it would be better to access all of them in the first place, imo.

Like in O4S as melee when I use Arm's length for Exdeath and then switch to Feint for Neo, sometimes I forgot to switch back...

I agree entirely with Daemic, I too feel slightly underpowered and it would be an illusion to tell myself someone would miss me if I wasn't here at all... Why? Cuss there's no one out there thats exceptional to the rest of the community...

Sure if you use your skills properly that can make a diffirence... I get told I'm a good healer quite often but its not satisfying for me cuss I do realise that a lot of healers are good and that doesn't make me much diffirent...

They have been moving in the opposite direction ever since the game launched - removing most ways to vary your build - so I'd say the chances of you getting your wish is about nil.
