Dumb banner popup
One thing (no, not only one) VERY annoying about the game is the "banner popup tip" about "click here for artifact tips". That thing pops up constantly, no matter what the battle outcome is, and obscures your view, etc. If it offerred something REAL in the way of helping it would be different, but all it says is to "upgrade your artifacts". Wow BIG NEWS!!! Another phrase for "spend money on silver!"
This should be made to popup less or actually have some real content.
