Usually, EIs are 20+ tokens, I don't think i've ever seen the whole set go for like in 10's low end. Unless magic happens, it will be so.
And event commons are part of event and something I consider immediately as event starts, and most people do (and half of after-event questions in feedback are about them!!), that's why they are event commons. But I suppose, it's fruitless to discuss this with you right now. Time will show how this goes.
