Okay, so I know the normal complaints can be levied against fight pits. Too grindy, too expensive, etc.
That being said, it’s still my favorite. It gives players who can’t drop megas a chance to participate, heck I’d say you could win without dropping a mega if your team grinds enough (unlike gauntlet). It doesn’t stick you with only 1-2 teams you can attack for the entire event (unlike kingdom wars). It truly allows for the most freedom and is the least boring in my opinion. I’d like to see more events like this, where chances are you can’t/don’t have to choose one player and hit him/her the entire time.
