That's unfortunate. For someone that doesn't have the Heroes of the North pack, and doesn't know what the skills are by name, it makes for a longer process of calculating everything. I actually wouldn't mind if the boxes become massive. It's like that with a lot of other MMOs and ARPGs
Only suggestion I have to make this Calculator perfect is to put the description of each power in it's popup rather than having to scroll through the wiki that's on the right hand side. Is this possible?
