2 ONLY if you going to allow for instanced so that multiple group/people can go in regardless of size. For example, most of the time when I go, I go in to solo #3 for coins (DNC/NIN). So I would hate for me (a solo'er) to go in and locking up the zone for an ally of 18 who would have to wait until 30min or whatever time duration that you're going to make it into, plus another 30min of zone cool down (the current cool down).

If that's not likely, then still with #1. Yeah, I hear and understand all the ppl's complaint about leechers. But would you want multiple solo'er to lock out the entire zone if the zone won't be instanced? Or would you rather take a chance with some leechers and pray your lot dont suck for that run?

Otherwise, get rid of WoE and put the coins drop off something else. And please do not make WoE an once a day thing unless you are going to:
1. Increase drop rate of coins significantly.
2. Allow for some mechanism of trading in coin with another coin that people are targetting. [Alternatively, instead of coins, make the mobs drop something that can then in turn be exchanged for coins that the end user can specifically seleccted. There's nothing more frustrating then needing 1 last coin of 1 type and only seeing and getting coins of other type.]
