the old days were definately good times,
i remember the crossroad raids that went so well we would head to Org and get our asses handed to us, back when there were only a handful of 60s on the whole server.
I remember mind controlling people in pvp situations and using their big abilities (warrior abilities come to mind but i can't remember the name)
I remember seeing a huge group of horde invade westfall and thinking i could take skulls when i was level 20ish.

I remember when i switched to horde i played a shadow priest, and i'll go ahead and say they were a bit overpowered right before the last patch came out that everyone got pvp gear with. Battlegrounds were still kinda new and i could take on 2 people with devouring plague before they nerfed it to shit. Man that one skill was ungodly. I thought i was really good at pvping but it just turns out priests were insanely overpowered at the time lol. good times, good times.

And the most rediculous, i remember rogues that got a new sword in MC and have used daggers the whole time, so they equipped the sword and leveled up their weapon skill inside MC cause they thought it was better because of the DPS than the dagger they were maxxed out on.
