Are you sure? For some reason, DF parties that I join are always near always unable to kill Titan's Heart... I cannot compensate for others dps numbers so now I am gearing my BLM up... FC usually no issue one... Also as a WHM, I require to compensate for people that cannot get out of the Titan AOEs due to lag and other issues.
In all seriousness, in a perfect party you do not need to be geared up. Parties in FC usually allow you to not be so geared up. But using DF, you would really want everything to be as geared as they can be, as you do not know their skill levels.
Good for you if you have no lag. Just check the multiple posts on this forum screaming about said lag. The fact that most have gotten used to the lag of FF14 does not make it fun to compensate for. And seriously ... Compared to near any MMORPG, FF14 is one of the most lag sensitive game I have played in a lot time. I think is mostly due to their game design.
Let me give you an example of lag that I find in no other game: Once I escape any AOE, it has become habit for me to cast any spell even if I just cancel it so that the server will UPDATE my position so that it does not think I am still in the AOE zone. Because YES, I have escaped way out of 1 hit KO AOEs just to die because opps server forgot to update my position in a timely manner. It is not funny that I have made it a habit to straight cast any spell once I "escape" anything. That is not skill that is compensation.
I find it funny that memorization = difficulty. No matter how hard the memorization is. Of cause any game encounter requires you to know what the boss can or cannot do. But I do not find static rotations a measure of skill. It is more fun for me if encounters have a random element. But I guess to each his own. Also no where do I say that Titan is easy. His rotations are punishing and increased alot by party inexperience, skill level of players, min. gear required (yes it is an issue in DF), lag and human error by all in party.
