The funniest thing your opponents have complained about your army or called cheesy

[Snake1311]

I had a Skaven player complaining about Cannons (new Empire book) being OP when he found out the cannonball hit the Screaming Bell and the rider.....funny enough he saved the Bell with the 4+ ward, but I managed to kill the Grey Seer

Except it doesn't, which means you've technically cheated :P the bell isn't a ridden monster and follows its own rules.
