to take exotica is virtually impossible, the only way to do it would be to build a legion stronger than the dysonians, so for example 50 rank 300+ players. Exotica is one of the best planets, so that is why its designed as a king of the hill planet. It takes a lot of work to get it, and you must use extremely effective tactics to get it. The rebellion tried tactics like distraction, but it didn't work. you need new tactics and strong players to have any chance of taking exotica
