This Saturday I went from level 15 to 17 in a couple of hours

In Crushbone (off of GFay), I was lucky enough to get into a full group in
the throne room. We killed EVERYTHING...If you can get as many bags filled
with the pads/belts from the cents and legos, you can level quick as hell.

Only big downtime is when someone pulled Dvinn from the tower. If he is in
the area...just save time and run for the zone, because some moron is going
to try to pull him.

at level 16...four CB belts = 1/3 of a blue bubble...basically just fill up
the bank and you're inventory and run to kaladim and change em in....big
exp...
