Basically, I strongly disagree with every single wish on your list.
1)I dont want larger empty zones - I remember the 10+ min run across the Karanas in EQ1 - I dont want that back.
2) Pets and cosmetics. I already see enough of that in the game. If anything I wish there was a way for each player to turn off seeing these as I consider it clutter. Let those that want to see do so but leave me out.
3) Different versions of a dungeon for each difficulty level … no thanks, I would much rather have more new dungeons.
4) Player housing. I dont see the point at all. I would much rather have a revamp of the inventory system to make that work well. A much larger shared bank with the AH interface would be a good start - drop personal banks except for btc stuff.
5) Guild ships got a huge revamp not many years ago. They are still not used for much and there is a reason for that. Just leave them alone and use the time for something that matters
Anyway, disagreement is good. Thank you for posting your ideas even if I completely disagree.
