For me :
Some classes here can't survive past 3rd wave without party buffs, like hunter or archer (might be also the case for ranger and mage)
The mobs after wave 3 takes a long time to kill, most classes get stunned from some waves which give difficulty and it is nice, the last two waves brings the most challenge because they hit you like a truck (12k to 15k damage).
Problem might be that casters spends a lot on mana pots due to their hp and the damage they do, party buffs improves your damage and allows you to spend less on mana pots
But there is also the case where after wave 3, one wave costs around 20k lens+ which makes you spend more CC, thats probably my only issue because it encourages to spend money to get those
Of course you can go with normal lens but it will ask you to play with double void or delusion which on critters is pointless
The damage critters does is not so bad, but maybe reduce the mob's crit res a bit (not 33% like on other mobs but around 10 to 15 % sounds enought) because right now a critter there is way less useful than casters and takes longer time to clean a spot in shinewood so it would make them a bit more interesting to play there.
Otherwise right now the way this zone has been made is nice, i love the way that new players and players that don't have OP gear can get it throught farming, it actually puts a way for them and farmers to get on the same step as the oldest players that have OP 8/8 gear, good way for them to catch up
It also opens a new way for people to get gold because they can farm lots of mats, open boxes, get tools, shards, runes and sell them for gold
Of course its only been 2 days since the update and we will have more ideas for a balance, or things like that, the feedback is also important for everyone who gets in there
