I would have to agree with the OP on this topic. I've been saying it since ARR 2.2. This game is VERY repetitive. I was well aware of the formula very early in the game and while I did enjoy playing it(I still do!) it's VERY boring. Let's look at the formula and see if anything has changed from 2.0:

We have our MSQ: Check
We have our leveling dungeons: Check
We have our primals: Check
We have our level 60 for tome grinding, tome gear, and Ex primals for gear: Check
then finally we have our endgame raid: Check

the formula is NO different in Heavensward than it was in A Realm Reborn. It is LITERALLY the exact same thing. MMOs are mainly PvE by nature if I had to say how MMOs are played. Before anyone says "there's always crafting, or leveling alts, or side stuff like gold saucer and chocobo leveling" yeah, that's very true. And while I do partake in some of it, it's not for everyone. On the topic of ENDGAME, you farm your weekly loots and THAT'S IT! I feel like what this MMO might need is more variety in gear and stat allocations. If all the best gear is a combination of tome gear and endgame gear, there is no room for anything else to be considered endgame and that's perfectly fine. BUT! It perfectly justifies that if that's going to be the standard, endgame is very boring. :/
