So the changes to RotB The event will become irregular again. The limit in force points is now 50k, instead of 30k. The event is a week long again. At least for this event, the 5* drop rate is 10% I'm not buying this at the moment because I've had over 25 boss battles over 3 accounts, one with a boss boost for 247 EP and no 5* yet. Based on math, there's a 7% chance of that happening. At least for this event, the boss boost hasa a 3 times higher chance of happening.
