Afaik it had some toughness issues especially in solo, but given the nerfs it may be good anyway.
However, the XP nerfs are pretty hefty after 70 - i don't have the link right here, but farming XP this season is supposedly pretty harder than previous ones are speeding high GRs will net sensibly less experience.
I'm not saying we won't see 4-digits players running around, but 2k looks pretty hard to get this time.
