Grinding HOT Mastery EXP - Where to go?

Anyone have recommendations on how to grind 4m exp fast?

DS meta (that is about 1M exp) , Bitterfrsots for night time, check maps for VB outposts events, run back to DS for another meta.If bored you can do easy minigames and check other LW2 maps for daily, metas etc.

also look at the 2 metas for TB and AB as the one ends just as the other starts - usually about an hour 2 do both. Also if you have alts they can do the HoT story lines. Just be careful not to burn yourself out with doing same thing to many times.

Easy method:Easy daily adventures and hero points. Ideally use experience boosters on a character and use that character for adventures only.

Still easy but more time involving method:Use experience boosters and run daily metas (Chak Gerent and Auric Basin both are very safe and fast, Dragon Stand is longer but yields nice experience too if you commit to it).

For sure the metas are your best bet...just don't forget the events that go on in the LWS3 maps. Those are helpful too, and they'll break up the feeling of grinding.
