Well, AJ was a hell of a lot more active back then, and the community in general was more vocal and engaging
A lot of those pages are s6 and whatnot as well with the good ol TSG pictures
Even then, wizards could be beaten, but a lot of caster comps had the advantage. The option to win vs better teams was there in wotlk. You could actually beat counter comps too.
You're being ridiculous. You can beat counter comps now too. You act like they have 100% win rate.
Not sure what you played in Wotlk, but there were plenty of times where you felt helpless against certain comps (at least I know that was the case if you weren't a Wizard).
Playing with a Prot Warrior was pretty much the only time that I felt strong against wizard cleaves in Wrath. Every other time was an uphill battle, and any mistake (ex. 1 CC landed on my healer without a trinket up and I'm not already behind a pillar) resulted in an almost guaranteed loss. Particularly against wizard teams that didn't have a mage.
Without the absurdity of Prot Warriors being viable in 3's, the expansion would have been pretty damn awful near the end. And you just have to look at all the LAN tournaments that were played after coL.Black fell off to see a perfect example. Nothing but casters vs. casters.
