It would be extremely easy for a pro sinx to break if he has solid back up and support. In PVP ladder only your name would be on top but in WOE you bring the entire guild with you. Giving the sinx the only ladder in WOE as I see it is a selfish act as you overlook the others who brought you to that point. My opinion.
Also, the sinx that breaks is already acknowledged seeing that his/her name is bc'd everytime he/she breaks for the guild. Just not in 2.0 though.
If we want an additional event, they can bring back that emp breaking event to be automated like back then. They should just modify the emp as it was in early RO days. It would be a plant type so all our damage is "1". Thus, any char has a shot in breaking it. But thats a different topic :P
