Anecdotal, to be sure, but last night I realized exactly how much I enjoy this game. I've been grinding ACN up and was doing finder pugs to break the monotony. Long story short of it, there was a Pld (Mind you, I was grinding up to 30 and up to Haukke Manor) who was trolling by jumping in and out of the finder and abandoning groups.
He did this once before and it completely ruined one party I had been waiting about an hour to get into. The second time he did it, I decided to take action. I whipped out golden carby and, to my great surprise and relief, the rest of the party was willing to stick around. You know what?
WE MADE IT THROUGH THE ENTIRE MANOR. Right up to the final boss, in fact! At the last minute, we decided to get that last bit of treasure upstairs just in case the boss was just unmanageable. We already agreed we had an awesome time in our three man party bucking the odds at every turn. It was one of the BEST GROUPS EVER! Not because we were all awesome (in fact, it was one of the members first time through). It was simply the fact that we refused to wait all that time just to let some complete jackass ruin the fun. We got mad loot all along the way, too.
Well, as fate would have it, there was a kind-hearted if not newish Marauder who was also in the Finder and juuuuuust showed up as we had eaten our Adam's Apples reluctantly taking on the boss fight the first time. The marauder was such a beast that we ended up wiping three more times (Kinda what happens when the bombs are still mucking about when the other adds pop and stick you to the floor. Lots of pain followed by a boom, that is.) But again, we stuck through it. We changed tactics a little bit and we won! We won an instance we rightly had no business winning without a tank and it was all because we grew our skills and understanding of the dungeon together.
But you know what? That wasn't even the best part of the night for me. It was one of the most spectacular experiences of my MMO playing career, but things got even better. I was so inspired by the utter carnage that Mrd was dishing out (essentially making it where the boss was taking so much damage that we were getting adds on top of the bombs and this was after the lamps seemingly double-popped on us!) that I decided to try out a lil bit o' mauradin' myself. Up til now, I've taken all three mage jobs to 30 (biding my time to get to end-game) and never even thought to go with a melee class in any serious manner. Well, as luck had it, a FATE popped on me at the ripe level of 3 or 4 with tons o little squaking sheep bounding down a hill. It was a sleep slaughter-fest with a whole lot of tabbing and a whole lot of killing!
I've fallen in love with a melee class! Had no inkling that I would before yesterday. I wouldn't have even touched Mrd had the day not transpired in any different fashion, but that's exactly what I did and it was pure gaming nirvana!! So, my advice to the OP is to take a day or two off from FFXIV. It is a game, not a job. When you log back in, do so Tabula Rasa. Clear your mind of what feels like a grind to you and, instead, seek enjoyment. Think outside of your box. Try something you thought you just wouldn't even like or at least do something different and new. This game puts so much on the plate and has so many different playing styles. The only reason it has become boring to you is that you have accepted the results you give yourself.
