1) NO TELEPORTING TO THE CROWN OF COMMAND.
It bugs me that there are so many ways to get to the Crown of Command without actually engaging the inner region: defeat the Lord of Darkness with +8, Arnkell, Dragonspire or Great Portal, etc. The inner region is a fundamental part of the game. Under no circumstances should it be permissible to teleport straight to the place where you can win just by landing there!
2) DRAGON TOKENS MAY ONLY BE USED ONCE, AFTER WHICH THEY ARE DISCARDED.
It is far too easy to become far too powerful by collecting dragon tokens. Add in Dragon Talon and/or Dragon Amulet, and you become nigh unstoppable against Dragon decks, which leads to rapid and unfettered building of your stats. As such, if you use a dragon token in battle or psychic combat, you must discard it. One use only!
There. I've said my piece.
Now, fire away and tell me how wrong I am.
