By now I almost emptied out the event store, and when I checked BoS to see how it stands, it looks like my soul count is higher than when I started sacking and frag counts are way higher. The only big thing is gold which is draining fast, and I'm down to one stack of skill shards.
Event obviously isn't aimed at beginners, but if you're willing to part with a lot of your gold it's very worthwile and manageable even for someone who is not a hoarder.
