A few things I've been thinking about, I'll start off with the new T1 boss, the Snarbolax.
Snarbolax:
The beast bells are a good idea but they make the boss too easy. What if the bell on the boss level was a much bigger bell (in order to stun the powerful Snarbolax) that took much longer to recharge? During this recharge time, after the Snarbolax is unstunned, he calls an endless wave of mini Snarbolax minions and disappears for a while. Just before the bell is about to become ready for use again he reappears with some ranged attacks around the edge of the fighting arena and comes in for a bit of a bash (all minions run away in fear of the Snarbolax back into the surrounding woods). Then you hit the bell, attack the Snarbolax and repeat.
Guildhall:
Adding various things such as a "Guild Bank" will make the whole guild experience more rewarding. Of course, Guild Masters should be able to select what ranks can take money from the Guildbank and have a list of who owes what.
Clockworks:
Adding the Dusker set of Wolvers would be a great start. Also more optional enemies (such as enemies that will growl at you to get away, if you get any closer, then they'll attack) would be nice.
East Haven:
Maybe a virtual tavern or something where you can get various stranger requests such as "give this package to Basil" would be nice. Maybe it could serve various drinks that restore amounts of mist energy?
snarbolax is tier 1 its meant to be easy
again with the guild hall junk dont care much i dont see the point of the bank
monsters maybe they are in the works we cant know
same with east haven i have no doubt its a new expansion for the future
