I don't know how recent of a change this is, but some of the changes with the new UI have made it impossible to bind the Shift keys (and just the shift keys) to an action. I know I personally found it convenient to put my block button there, and I don't quite understand why it was changed. I would like it if it was possible to undo that change.
Hey, Spiral Knights.
How about you do your job, and not make this game a load of crap. (:
Take into consideration what PLAYERS are saying and fix crap, instead of doing the opposite.
Thanks, :o~
