It´s hard to accept for you, if others are better at your beloved game hm?! Never said i´m a pro and never said i don´t do mistakes. But FF14 has more than enough players, which are not able to get more than 3 mechanics into their head. Or why do you think so many keep running around with Bots or Macros and then they´re proud on themselves and afk in Limsa with their weapon-skin?
Your claim let me highly doubt you´ve played further EC. Ever tried S&V or both Dread-Raids? S&V had 7 unique bosses with different mechanics / puzzles... some of them has been even doable in different ways.
What is "more life in them" in FF14? More graphical eye-catchers? Multiple bosses or adds are rarely a thing or just be there as short DPS checks. At pretty much any major mechanic, the boss jumps into the mid from by itself. If SE thinks "oh that´s too hard", they make it untargetable on top. I really don´t know what your claim "more life" should mean.
Skilltrees changed the classes somehow and all of them has been viable. They didn´t mirror each other either. Yeah the DPS speccs made up between "burst / dot / aoe", but they didn´t played too similar too each other as they do in FF14. If anything only Juggernaut and Marauder has been very similar in their execution, but Mercenary and Tech? Assassin and Sorcerer? Operative or Sniper??? Same counts for their Republic mirrors... All of them offered some unique playstyle with the possibility to adjust to your preference with the speccs.
Please don´t tell me FF14 does it better to focus on classes with a core-design, when homogenization is everything we have. Look at tanks... how long are so many DRK mains upset that it´s a 2nd WAR? What about healers... 1 attack, 1 dot, a bunch of oGCD´s? SGE is even called a barrierhealer with less barriers then standard heals and sits on the same gauge as WHM does? And DPS? What is still unique? Mudra, maybe Redmage with his swap between range / melee? That´s it?
