Typically we don't really like topics that make multiple suggestions, but since these are all so closely related it's good and actually preferable. Thank you guys for your efforts. :) I just encourage everyone who replies to consistently number the different topics you're discussing according to the first post.
As for the suggestions...
1. Emp HP: Stays/Lower/Revert to 250m: We're planning on reducing the emp's HP, but it will never go back to what it was. Knowing this now, it'd be great if people could suggest exact amounts for the emp's new HP!
2. Castle Drop: Rares, tickets: We've been discussing increasing the drop rates of the castle drops, though it wouldn't be by too much if we did. Feel free to discuss exact drop %s because that would be most helpful.
3. Woe Schedule: Timing of the WoEs, castle numbers: Okay, we're considering adding new times and new castles. I know Lenneth has made a time suggestion of 11pm, what do people think of that? What day works best, etc.? We'd need a lot of feedback on this from Asian & European players. It's unlikely we'd take a castle or two away from American WoE, we'd be more likely to add a new castle with new drops.
4. Alliance/Guild Cap: I'm personally not sure what I think of this. Generally, we don't like to interfere in the gameplay in this way. In the past, these things have a way of working themselves out in a little while. If not, we may have to do something, but that would only be as a last resort if things got bad.
Edit: Also, I'm pinning this suggestion topic. Ensuring we provide a great WoE experience is a top priority of ours.
