The reason 20s are XP off is that max capped accounts, 60/70/80, and in this case, 20, were twinking and decimating leveling nubs in those brackets, well maybe no one did 80s yet, but that was the reason for it. 20s are an unintended consequence, but not one Blizz has any plans to rectify. 20s were never any good at PvP. They used to get destroyed by 29s.
Perhaps circumstances were different in the States than in Europe, but 60's and 70's were never 'decimating' people in the vast majority of the Battlegrounds they played in, as in all the Battlegrounds except for AV they were lowest in bracket, with an up to 9 level difference, and their numbers were rather limited even during CtA AV (at the most 10 per side, and the number of not just GM gear toons - at the time outclassed by Hellfire Quest rewards - being a lot lower).
The biggest issue with 'AV twinks' wasn't so much that they were stronger than the CtA XP-hogs (outside CtA, AV only popped in two Battlegroups) but that they, like the 'regular' ie non-CtA AV players, had a different preference on how the map was played: XP-hogs wanted zerg games ie 'Win by general', the other groups 'Win by Reinforcements' (and the resultant summongs etc. that regularly took place).
With Twinks being actually strong enough to influence the battle (certainly when supported by 'regulars' like myself) towards 'Win by reinforcements', and most of them (like 'regulars') prefering this strategy as you could get the zerg-crap at end-cap, this was bound to clash with the heirloom-clad XP-hogs who basically wanted the same game-play at mid level as was already available at end-cap.
Just as 'new players' were only used as an excuse to kick out twinks so alt-levellers could slaughter newcomers etc. themselves with their Heirloom gear ('twink-in-a-can for those who actually hate playing low level toons') , the whole 'will somebody please think about the new players?' riff about the AV twinks was just an excuse to let those with end-cap toons dictate the game-play at other parts of the game as well.
Note that I am not exactly alone on this as far as the AV twinks are concerned, even friends who basically detest twinks were never bothered by the AV twinks as they kept content alive that was zerged to death at end-cap.
