By what measure are we gauging the size of the patch? If you're judging by fights, sure it's just a few hours of content. However, if you look at the little QoL tweaks, new tome accrual, wondrous tales thingy, several new tiers of gear, apartments, housing adjustments etc. It's a pretty "big" patch, and should provide things to do for some time. For those who dabble in all the game has to offer, there's plenty of new stuff.

I do, of course, respect that some players may feel short-changed, but have you considered that any content only lasts as long as you let it. That is, if you log in after maintenance with the goal/purpose of clearing everything as quickly as possible, then that's exactly what's going to happen.

That's just my onion served fresh.
