Totalbiscuit is a total moron though, he's forgetting that 'paying 2 win' in this game is still impossible. Say you spend £1,000 getting a maxed out castle with maxed out upgraded mobs and bosses, then what? He talks as though your castle level won't change. The castle levels skyrocket with significant upgrades. Great, again lets say you've spent £1,000 maxing your castle out completely, enjoy getting spammed by level 30 heroes who smash through your defenses anyway...
Always said he was a moron, this just confirmed it. <3
