1.) Make a free(first cast of the hour) unlimited number of teleports to Arcane Tower. After the first cast within the new hour make it cost 5 silver. Add the same effect for the Homestone.
2.) Make it were we can add markers on the minimap. I'm not sure about anyone else but the minimap is hard to use for me and having a marker pointing me in the direction of where I need to go would help a lot.
3.) When adding a friend make the other person accept it before they appear on his/her friend's list.
4.) Instead of 1.) just spread more Dragon Handlers out across the world and have a heavier tax for using them.
5.) Have an enable/disable option for the big lettering on the map.
