While they might have changed it, I think that, for a lvl 88 mob, its about 21% miss chance with spells.
Wowpedia/wowwiki hasnt updated those pages in YEARS. Also, there is the new crit depression- you need 5% more crit to get to crit cap with cata bosses.

Haven't tested melee miss chance yet though (just guessed at 2.5% more hit/exp needed per level).
What should be "fixed", that's penalty for leveling. So when lv90 player fights lv80 mob, he'd have same crit and hit chance as lv80 player with his ratings. In other words, ratings should check for mobs' level, with haste/mastery ratings and mana regen to check for level of zone. Losing power when leveling is very counter-intuitive and bad.
Currently trying to experiences all classes at 100. Count so far: 3.

And no, they don't need to 'fix' anything. Why ruin people's fun? How does it effect you if they go back with ~1/2 the HP and kill the things you're no longer killing?! Hurt your Epeen too much? Poor you.
Just wanted to point out that I am completely in favour of them removing/fixing these 409 items (and the ridiculous avoidance scaling at level 80). As fun as it is to play with gear like that, it has really ruined the 80 bracket in both PvE and PvP (in my opinion anyway). I brought these issues to light during the beta but nothing was done about it and I've been trying ever since to get them changed. If they're here to stay, I at least hope Blizz will consider making an official change to allow 80s into 85 raids, so that we have a permanent playground to put them to good use in.
Though I am a proper fan girl when it comes to watching Aelo solo stuff (probably because I sometimes get a first row seat whilst being dead on the floor) as well so watching his whole guild kill things is even more impressive to me.
Secondary wieghts have a lot to do with dps. As players leveld from lvl 85 to 90, the amount of a stat granted by a rating decreases. The amount of rating on a piece of higher lvl gear also increases, but not at the same rate as the stats decrease. Thus, a lvl 85 in full H DS gear might have 50% crit, 40% haste, hit/expertise cap, and an equivalent of 20 points of mastery (old mastery style), when they hit lvl 90 in the same gear, they have 10% crit, 8% haste, 1% hit/experise cap, and about 12 points of mastery compared to 20 (Mastery doesn't seem to decay as much when leveling due to the original 8/2 points of mastery). If they had the lvl 90 quest gear, they might have 17% crit, 12% haste, heroic dungeon hit/expertise cap, and 14 points of mastery.
Finally, AP/SP coefficients on spells change as one levels up. This was extremely noticeable when lvling from 80-85 as a healer, and gearing up. Even in heroic DS gear, my healing power was merely 2.5x what it was compared to lvl 80, very small when compared to tanks/dps increase of 5-10x power (EH/DPS, essentially). The reason for this is that the SP/AP coefficients on spells ALSO cause a decay in the effects of a primary stat as one levels up.
Remember that as you get more of a primary stat, the overall value of secondary stats increase, leading to an exponential dps gain. Also remember that as you level up, the relative value of every stat greatly decreases. Thus, it is quite common for the top players of the previous expansion to preform dps numbers, equal to or greater then that of the average players of the new expansion.

interesting thing to try, happy for you it worked out so easily. But seeing the stats and as you said that it was "easy" I don't think it is particually impressive outside the fact that you've though of doing this.

He has ganked level 90s that have tried to get easy lowbie kills.
If I could de-level one of my currently unplayed characters I would happily make it an 80 twink.
