If it's a full team of Preds that's all alive and healed? Then yeah, if you're not confident with your skill/the team you have then it's not worth the risk, especially cause that team has probably player together all the way to Predator so they'll have their synergy and tactics down to a T.
If it's one solo queued Predator with average teammates, or if the team is weak or in a bad position, then go for it like any other squad. They're just players like everyone else and can only do so much against a semi coordinated team that can get the advantage over them. Just don't blame me when the last Pred manages to 1 v 3 your entire team :P
