Endor Escalation - "Requirements"

Star level for these things is more of a requirement thing than a real indication of difficulty. You need 5 4* Ewoks as a gate to participate. It was 4* because there were only 4 Ewoks before the new ones came out so you had to use a new one and they had only just gone to the board. So setting it at 4* let more people participate in the event faster.
