I have a question, will thare be any shield or some kind of buble spell? That would also be a nice adition. Also customizing at least the shield would be cool (I mean do a drowing on it) like in minecraft, that would also be good for guilds because they can do the emblem on them. I don't think the map will be that big in order to add towns that any guild can fight for and capture it, but it would be cool.
Edit: Another question I don't think it's a good one but well: will you be able to kill npcs or at least try it? I don't think it's good because if you kill a inportant npc for a quest that would make you and other people unable to do the quest, it's just a thought tho.
