...Fact is, the 4e crit rules mean that the Orc Greataxe Problem just doesn't happen in 4e. Especially at epic levels, an extra 5d6/6d6 on a crit isn't going to break the bank (by meaning a lucky 20 kills the PC straight off by doing 1.5* his total hp)....

But do remember that one who really beefs up the effects of critical hits is likely to also take the epic (weapon group) mastery feat that lets them have criticals on a 19-20. The good news, though, it that only happens at epic levels and so that pretty much prevents abuse.
The big power creep for 4e may very well be if WotC allows some other power to stack with that feat. That would be... bad. Very fun for whoever gets it, but very unbalancing.
