For example i may want to more than 5 of the skills when using the bow. Say i want to use all 10 and 2 ultimate both with bow, equip 2 bows. I most likely wouldnt do this but it would make for some very interesting gameplay especially when being in pvp and going against someone for a while. When you switch weapons the other player would have no clue, theyd be expecting you to use the same powers youve been using but infact you changed all powers.
