What's the point of random single champ arena def in Stoneskin?
I'm not talking about traps, with champs that could win from their armor set, like Stoneskin Gaius or even Stoneskin Paragon.
But I've met so many ultra slow (so their Stoneskin effect doesn't dissappear for a lot of attacker turns) random champs with absolutely no chance to win the fight or force a stalemate once the Stoneskin effect is gone. What's the point of this? The fight takes a minute for the attacker instead of 5 seconds, but the attacker allways wins. What does the defender get from this? Do they print the lists of people who attacked their arena def, put these lists as a wallpaper in their room and say "I've stolen hours of lifetime" with a diabolic grin?
Why would anybody who is not a complete [insert word the mod would edit anyway here] put an Armiger with a full Stoneskin set as arena def?
