Why should I be excited for Grind Parties?

[Xenor]

The ultimate holy grail of MMORPGs, making grind fun.

Why? I'd rather they made the ranking up process so much fun that you didn't see it as a grind. Imagine running a dungeon like Darkhold for example, spending an hour in there and come out with 25k SP plus an item if you're lucky. They should have made that ogre drop 5k SP and Batraal drop 10k. Have half a dozen of these designed for levelling plus other non-grind content and you're on to something good.

That may sound like a good idea, but would probably end up with players camping the same dungeons over and over anyway. Grinding them. Having dozens of dungeons is like having dozens of grind camps. Boss battles end to be similar if you do a lot of them...
No, the best solution is still to make the dumbest, simplest mob actually unpredictable in its behavior and uphold party role specialization to the utmost.

My favorite battles in WoW were the ones were team roles were essential and my favorite ones in FFXI were the ones where the mobs were hard to predict. Goblins in the Valkurm Dunes, Divine Might boss fight. Those are only right directions, imo.
