Karazhan was its own tier-- it was either you combine around three successful Karazhan raids and went on to Gruul (or if it took long enough, skipped to Serpentshrine or The Eye, or even later, Hyjal or Black Temple) or you didn't and maybe went to Zul'Aman (if your raid actually stuck around that long without going to the other places).
So you'd rather have each xpac up 2 dollars, and pay more than have them do it all at once? So you and other people had more to complain about each expansion? No thanks, the price hike brought enough complaints for every other xpacs and then some for the next. I'd prefer to pay less the past few and then pay more this one, because whether or not they did it each xpac increased by 2 dollars or something, this xpac would have still cost the same.
LOL
I actually honestly forgot to count ToC. I think it says it all about my opinion of the raid
I stand corrected though, yeah WotLK had four tiers.
TBC had three tier set (T4 to T6), but the T6 gear covered two tiers (Black Temple/Hyjal and Sunwell Plateau). I guess people can debate if Sunwell Plateau was truly another tier, but I think it was far enough above the previous one and big enough to deserve this label.
