I agree, when I bought this game I thought it was going into a completely different direction. To see I've got this game almost 4 years and how little advancement exploration has seen makes me sad. I honestly have given up hope for Ylands to become what I thought/hoped it would become, and just like DayZ it seems design mistake on design mistake. I feel that the exploration game mode has got moved to the side in favor of the editor and the mini games made with the editor, which may have to do with trying to push mobile where there is more money to make. The whole cosmetics/coyns blunder also failed, as did the dedicated server thing. Does anyone actually think any of these things through? The biggest ingame issue for Ylands I think is the split between the editor and survival. If it would be possible to switch to editor-like building in the protective barrier, that would give people more and easier building possibilities, especially if you want to change things. Building a house is already difficult, but having to rebuild/change it is a lot worse. Building in exploration is a chore and because of that all I see on servers is just some crafting stations on the beach. There are almost no game mechanics that need you to build anything nice. I'd love to make a greenhouse to grow food on the arctic but why should I? I can grow banana's at -30 degrees. I'm not sure how tied in the Ylands team is with the DayZ team but it seems that not much was learned from the DayZ experience overall.
Edit: The topic is actually called "What makes you enjoy Exploration mode?", so I'll answer that as well: I really like the lush environments and the actual exploration. Working the voxel landscape has so much new potential to make amazing things, which I would love to enjoy together with my friends or in an online community.
