This is all true but in FFXI leveling content was equally spread out you just needed people who could learn from their mistakes and work as a team. In FFXIV the leveling is mostly solo until 30 where you grab seemingly random classes and pull/aoe mobs until 50. When leveling Monk in groups I might aswell been PL'd because i barely got to hit a mob before the mage/archer storm killed them. Leveling has no structure its just the same with and without a PL only difference is it goes from 2-3 people doing all the work to just 1 person doing all the work.
There is little learning involved in XIV's parties which is unfortunate and hopefully fixed one day. When leveling conjurer I went 1-50 playing the class like a BLM because there was nothing but Conjurers seeking and we just stonara/aerora everything down in seconds over and over until 50. How does this teach me how to heal CC/AV/Moogle/Ifrit/Garuda/DH?
