Yup, it's a good idea to test PvP given all the equipment changes we had. The event you talk about is now called Qlosseum, BTW, and I'll be spamming it today and tomorrow.
I dont know hows that work. Can you give some insights? Does Qlosseum shows on some sector and there players can skirmish against eachother? That would be awesome for Qlosseum to have some sheudule or warning when it will be available. People need to plan their time to plane their PvP we all have different time zones, jobs and daily choirs that we need to plan out for such kind of events make any sense at all.
