Suppose that you have a team consisting of four sirens. Each of them wear a BotA relic with 47% cooldown boost. Here’s the question: What happens with the cooldown if all of them decide to wear a Leg Binder with 29% team cooldown boost?

BL maths often mean diminishing returns, and iirc, that’s the case with cooldown. So, at which point will the relics or COM’s be a waste? Has anyone done the maths on this, or tested it?
