All your calculations don't take this into account.

tl;dr - Crits mean more for flares than they do for blizzard/fire2s. The PPS should reflect that.
If your looking solely at dmg on flares sure, crit is the way to go, what you dont take into account on the "big picture" is Cast times.

Bigger numbers does not equate to higher dps, Fire 3>Flare>Blizz 3 would be less damage than the "normal" Aoe Rotation due to Cast times and waiting for that mana tick after a flare.
