If by stamina you mean energy... then you couldn't be more wrong. Lots of people grind rep, and PvP score... and even if you don't you should do Ascension tower... and that can easily burn through all of your energy.
Logging in using Kongregate Account is different than logging in with your elements account. The two are separate, so if you log in with the wrong one it will appear as if you have never played before.
I couldn't agree more. You can always change your keyboard, but that is a pain. Being a Tetris player I am use to using ASDF for moving and HJKL for spinning, with G being for the drop. I would really like to be able to change the layout, so I could use nice, centralized keys. Also, HJKL is used in a ton of other programs and languages, including the almighty text editor, vim! (Though emacs is good too)
Well.. I'm not going to lie..Chosen one is pretty op...Your best when facing it is by using Wheel of fortune, The magician, or Disinformation...though 2 of those 3 are kinda pay to win cards..As for Sanc...well... just try not to put too many creatures in the same row...
Trading guns is sorta pointless. It defeats the point of separate classes. Its the same reason why mastery does not cary. It may be fun to have it as a bonus feature so you could trade between two level 100s, as that takes a lot of effort, and time.
