that's very interesting... Reminds me of my battle today.
My friend and I was in the elevator and we were full... low and behold, 4 jump out at the last second and only 4 of us in to fight. Well thank goodness my friend and I wound up on the same side together. It was 2/2 against the cogs instead of 4/4. The other 2 toons on the other side didn't last long at all. My friend and I lasted through the first phase of cogs, barely... then we teleported back to the playground. It was exciting to play without the 8, but very annoying not being able to go all the way and having to replace parts and merits. Nice learning experience and in the end I was proud of us two making it through what we did, it was close a few times... especially when goggles didn't lure more than once.
Happy cog hunting all!
