This is a little something about back in the day. Everyone has those little bits of nostalgia. We also seem to easily forget some of the ridiulous things that went on with our classes. I am going to start out with some of my observations, and hope you add more to the comments, which I will add to the actual article.
1) Warriors were THE ONLY endgame tank. Feral Druids and Prot Pallys were jokes pre-bc.
2) You could not charge in combat. I dont know how we lived without this.
3) You could not Thunderclap in Defensive stance. This is one of the things that made warrior multimob tanking so ridiculous. Tab sunder, tab sunder, tab sunder.
4) Arms was an awesome PvP tree (wasnt that long ago).
5) Leveling was terrible....I mean really bad. If you pulled more than one mob you would probably be corpse running. You went through tons of bandages, potions, and food just while questing. This is probably why it took me 16 days /played to get to 60 on my main and about 8 to get to 80 on my Druid (and I was a noob).
6) Prot Warrior DPS was terrible. Threat modifiers were all over everything. T5-T6 gear, while tanking putting out maybe 300 dps. When you were not needed to tank a specific encounter, you dual wielded and spammed devastate.
1) Paladins were healbots, and only healbots. If you were Prot or Ret, you probably would not be raiding. This continued for Ret a lot of the way through the burning crusade.
2) Paladins were only Alliance. There were not fruity Blood Elves running around making a mockery of our Holy Warriors.
3) Seal of Blood was Horde only. They gave Horde Ret Paladins the best seal in the game. That was a major blow for prospective Alliance Ret Paladins. It was fixed when Seal of the Martyr was introduced.
4) In BC, Prot Paladins were highly sought after for Heroics and regular instance runs. They were the only class EASILY capable of holding aggro on multiple mobs. Thank you consecrate.
5) You could tank better as Holy than you could as Prot or Ret. I believe this was when consecrate was way down in the Holy Tree pre-BC. Yes, the Paladin trees were that screwed up.
6) Paladins could fear forsaken players because they were considered Undead, and not Humanoid.
7) 5 minutes blessings. Yes 5 minutes. That is a lot of rebuffing. Buffadins for the win.
1) Warlocks were pretty much a free HK at the beggining of WoW. If anybody saw a flagged Warlock, it was LULZ DEAD.
2) Warlocks became the most overpowered PvP class around the beggining of BC. This led to nerf after nerf after nerf.
3) They spammed one button over and over to top the meters in BC. Sacraficing your succubus and spamming SB was the only way to go. If not, you didnt get to go (unless you were the lone affliction curse bitch).
4) Fear lasted a lot longer than it did now. People used to keep me hydrated with all of the fear QQ.
5) All of your pets were useless unless the were sacraficed or acting as a mana battery in PvE content.
1) Pre-BC, Druids were healbots and only healbots. They were in the same boat as the Paladins. DPS and tanking sucked in both trees.
2) We did not have an out of combat rez. If you wiped in an instance, the only option was to corpse run.
3) Everybody leveled feral and respecced Resto at level cap.
1) Non-Combat pets took up an inventory slot. So did mounts. It was pretty common for people to toss their regular mount once they got their epic mount.
2) If you wanted to do a BG, you had to run to the area where the BG was located. I was around when WSG was the first BG. That was a crappy run from the eastern kingdoms.
3) Alterac Valley could last for days on end. You would actually get to see the special units summoned into the battle. I remember the first time I saw the Horde's giant ice guy. We died over and over before we finally took him down, but it gave us a great sense of accomplishment.
4) Reputation gain was absolutely ridiculous. My main is still Honored or barely revered with most of the main factions after all of this time.
Feel free to add some more for classes/races/misc. I left the other classes for those of you who remember what it was like!
