A decent chunk of players, including me, really hate the current way boss is chosen. Anyone can have enough dna for boss, then just click it faster than the zombies that are actually killing people. I suggest that this be changed.
What if you could claim a boss instead, mid-wave, as long as you have the DNA? This would be much fairer for the people who actively attack humans, and would make it feel like more of an actual competition, rather than a stupid precise timing.
