We announced the rules of the event upfront mate. Playing it or not was your choice -- you knew the rules.
The leader choices were made before the event, no one complained then either.
I get your frustrations mate, but it's a game, this was a new, experimental event meant to be fun. It's a shame what happened, but in the end we try our best to create a ruleset we think people will enjoy and then it's up to you to play it or not.
We did not see this coming - if someone else did that's on me, because I didn't notice it.
