First off, I suggest putting Super Level Scrolls in the Event Items forge. Make it like 200 ECs or something. Would make a nice sink to put ECs, making ECs more valuable in the long run.
Secondly, in order to get more people to vote, I suggest putting a 100 Epic coin in the boutique for 5 gold or something, may encourage more people to vote.
Thirdly, I think rancor events need to be bigger over a larger area. Sometimes we never got a chance because there were a lot of people and few mobs to go around.
Lastly, I think that the base quests should have a bigger reward to encourage more participation. Make some of the buffs better, increase the experience, give then an old epic coin for doing it. Or more experience. Something like that.
Just suggestions.
