What? Really? That's not a power-up. That's an inconsistent comic book fight that happens all the time. Logan also somehow manages to hold Cyke's blast with his thin claws instead of flying off 50 feet or getting his flesh teared off like logically should.
Cyclops has, if anything, gotten weaker. Seriously, when was the last time he did anything impressive with his beams? He has gotten one upgrade in his entire career(Giant-Size X-Men #1) that most writers forget anyway.
