I think them losing Berg is a bigger loss than us losing Mak. If we had my boy Mistakidis, I'd feel better about it. But lacking that, Pelkas will almost certainly get a start there.
A draw vs AEK and a loss vs PAO will still probably leave us in second place. Since the tiebreaking criteria is head to head (and I believe we lost both games vs PAO this year?), we need to go for the win and hope that they somehow draw vs Panionios. Either way, this playoff is still very much open.
