I agree part should be rolled back. I also believe some things needed nerfs (and some areas buffs). Mistlands was tolerable after learning the ropes, however, it became a tedious grind.

My wants:

Tone down the mist a touch. Options to cut thru the mist, or just make the mist a bit less hard to see thru, not much, just take the edge off.

I really don't think the mobs need nerfing, however the frequency coupled with their difficulty made the grind annoying. Lower the spawn rate somewhat however, I think this means the need to add young seekers that have a chance to spawn the normal seeker drops at a lower rate so it doesn't make the grind any worse.

Something to help with stamina. Nothing huge, just something to aid with regen, or slightly lower stamina drain. While I generally like how the game is set up, I do feel this needs a tweak.

In general, I am happy with the game, this patch was a very sharp spike for difficulty. I haven't gotten to play the new seekers, however the changes sound like too much with regards to the nerfs. I feel a few subtle tweeks elsewhere would be enough to aid the gameplay without too much issues for the wide spectrum of players.
