Inn System? what is this?

I thought this was one of the ways they keep people from grinding 24/7 for a minute. Then I saw that you could play other characters. Pretty ineffective system, then.

It helps casual players because look at it this way:
-The way WoW implemented it, it takes ~2 weeks to accumulate 1.5 levels worth of 2x EXP. The thing here is obviously, a person can gain way more than 1.5 levels in 2 weeks; hell, a person can gain 5-10+ levels in 2 weeks. Are you saying that 5-30+ levels is somehow inferior to 1.5 levels? :f6:
I wouldn't say the system is ineffective. For me, it actually encourages people more to only play after gaining so much rested EXP because it gives them a rush. Leads to more casual playing longer over time rather than at one insane grinding session. I see nothing wrong with such a system.

Oh, so you play less, but get heightened Exp when you do play? ;o

Yes, but of course they make the system so one who grinds will obviously level faster than people who don't play for a few weeks. Again, helps casual players more because they will remain playing over time, and for the really high levelers it gives an incentive to keep playing since a few weeks of rested EXP can mean a lot for the amount of time they need to play to level.
