Nod, I agree with Muod, most guilds do seem to cap at around 1.5 mil, so obviously, having a cap of 1.5 would be even for most guilds and wouldn't stop most from leveling at their max or close to it.

I don't see what the big deal is about the cap anyway, I mean, it took me like 6 minutes to properly cycle my cleric, it may have even been more, I found it such a pain. I could just imagine how long it takes a CL or an AM...

The cap in conjunction with other things, like static quests etc might spark some player interaction.

"Hey, I don't need to cycle right now, let's go and kill someone, or make something, or explore someplace"

I'd like to see that.
