I'm guessing you didn't even read the first reply to this thread (mine).
Polymorph just requires that you change your size modifiers, not remove all stats.
Like I stated in my first reply, a Great Wyrm changing into a Human would have 29 Str, 10 Dex and 21 Con. That's as good as some combat-focused players are 20th level, and it's before any spells or magic items.
3e rules for changing forms was different, in that you got the physical scores of the creature you changed into, so perhaps that's where you are thinking of the "normal human strength".
Double-edged sword: a 5 Str Druid used to be able to change into a terrifyingly scary Polar Bear and ruin the enemies of nature with 27 Str. This has also been removed.
