The biggest problem with the Kickstarter page is you don't get too good a sense of how different it will actually be from the myriad of WoW clones that have come and gone over the years. If I didn't know much about EQ or VG and saw this page it would seem like a pretty standard MMO to me.
Very early in the page you should make it more clear what the design principles are; something like:
- More content from 1-50 than other MMO's, not just a race to max level
- Non instanced dungeons/content
- Soloing not the primary method for leveling, no standard quest hub grinds.
- Most low to mid level mobs will not be a cake walk like other MMO's
More specifics and not "the game will be harder".
