I was wandering how far I can go over 50 even before finishing the 2.0 storyline (I last left the storyline one quest away from Garuda, the 3rd primal battle). Just thought I'd try this with my alt (currently lv49) and get a comfortable headstart on the HW storyline when that comes around after 2.55.

This is taking into account the challenge log entries, dungeons, fate battles, beast tribe quests and leves (the whole hunting log for ACN is complete).
