Will you quit if this game becomes raid-centric?

Because in XI the chests weren't in 5 minute re-entry instances zone you could spam. And low level? The content at any level should be rewarding.

If 50 content isn't rewarding at 50 how is 75 content going to be rewarding at 75?

I duno dude, I dont' have a crystal ball..

Of course as has been pointed out you are evading the fact that this game doesn't have much content, so current content is on a timer suitable to the needs of the player base, as more content is made available there will be less need to spam the same instances over and over unless you are after a particular piece of gear and even then they may change the reentry timer in the future. We just don't know what changes they plan to make.
