Bro, we've already established you're posing as some experienced vanilla player.
You are the one who is posing, trust me. I already posted my T4/5 raid geared TBC character on retail, I just burned out from pally healing, it was way too simple, and the demands of a hardcore raiding guild, and quit raiding for a while, so I didn't go to the T6 raids. I can't prove what I did in vanilla because it seems the armory doesn't seem to keep track of what you did in vanilla, so I also posted my BWL/AQ40 geared priest from Kronos, so I have very recent memories of what raiding and vanilla actually is. Yeah, the numbers might not be exactly 100% Blizz-like, but they are close enough, the problem isn't the numbers. Like I said, it's the burn out from daily rotation of raids, the degenerate meterwhoring gameplay and loot councils that reward such behavior, and the grind for consumables if you grind (I don't, I work the AH instead, but the economy is extremely limited). These things were true in vanilla, especially the raid rotations, you needed your enchants from ZG, your materials from AQ20, your legendary mats from MC/BWL etc., the numbers are irrelevant in this case.
Anyway, about the 5 mages at AV thing, here are your citations ->
Improved Blizzard and
Permafrost
5 Mages spamming Blizzard + the archers at the towers spamming *very* damaging arrows makes for a bad time. You can't just "mount up and rush them" because movement speeds stack multiplicatively, not additively, so 200%*0.25 = 50%, so gg. This coupled with the fact that AV
heavily favors alliance. Horde can also exploit the mages thing, though. I don't know what more citation I can give you.
I am the only one who keeps posting screenshots, videos, armory links to try to "prove myself", everyone else who votes me "retardred" or "shit" is trivially shitposting and saying "nu'uh, vanilla was great!" without anything to back it up, so maybe think about that.
