Hyperion is very expensive to use. It is very powerful, but the player cannot solo more than a single fleet (of about 25 ships) with one before CR decays too much. As for AI, it captures points much faster than anything else, but it is otherwise too cautious a fighter to be very effective at anything else.
Phase Teleporter is overpowered, but if has a delay, then Hyperion needs to be cheaper to use. Also, Afflictor, yet another high-powered ship, can interrupt Phase Teleporter. AI Afflictor is a very dangerous opponent for a playership Hyperion. Getting disrupted means Hyperion can be two-shot killed by double AM blaster from Afflictor. AI Afflictor is good at that.
