When it comes to PVP events, I like to use them to see how I fare against other players, level and power-wise. With the events that have boosting (ragnarok, cerb, baal, heaven palace), I would like to see who of those have boosted at the very least, or maybe a percentage listing by their names on how much they have boosted, so if I'm going up against another player of similar level/power who is beating me severely, I could tell if it's because of boosting. Normally when that happens, someone beats me, I look at their profile to see what they are doing to try to improve my own character. It would be handy to know if I'm beaten because of what they've done to their heroes, and not temporary inflation.
