XionAvalonArcadia, please do not quote me and change my words, if you must, use "snip" or a blank quotes, the very fact that you took the time to change my words into something that I never said just shows how mature and willing you are to actually listen to very valid problems that this game will incur in the long haul. Let me make it a bit clearer for you, this game offers ONE challenge: organized memorization.
Like many people are stating the ONLY way to make the game more challenging is to change it before it becomes even more of a problem. What I mean is that the very function of endgame mechanics need to vary up, like my Titan EX example, it was paced well and was challenging at the time of its release, however because the game so far has only been able to deliver this one challenge to the players in the endgame raids. Honestly Cerberus was one of the best mechanics ever put into this game as it was new and refreshing from the same old stuff we have been doing since the first Primal battle. If they continue to develop content that only offers this kind of gameplay there are only a couple ways they can make it more challenging:
1) Make mechanics stack on top of each other or have slight overlaps requiring the perfect precision in order to complete (from the first EX Primal to Bahamut Prime we have seen this as a factor as mechanics are getting closer and closer to one another)
2) Make more dodge/stack mechanics appear in a single battle (which we have also seen from the first EX Primal to Bahamut Prime)
Side Note: Frankly I think the Dreadwyrm gear is the worst gear design this game has put out save for the Magic DPS Soldiery Tomestone gear. So no I do not see someone running around with "shiny" gear and go "OMG MUST HAVE IT AND I DONT WANT TO BE CHALLENGED TO GET IT!" I want a challenge, however I don't want "Final Fantasy XIV: Rock Band: Can You Hit All The Notes Edition" which if change does not happen is where it will go.
