Well, I am going to create my very own base in Hoenn, but the matter is that others players won't be able to see it, I know that because I see many players entering to trees or holes in stone (Where I suppose their bases are), but I cannot enter them. So, I suggest a button when watching a trainer profile (Or an option in the scroll when left clicking a player) to visit his/her base. What do you think? I think it is a creative suggestion, idk
