People are so blinded by nostalgia that they don't understand the gravity of this situation. Yes, let's keep it as blizzlike and vanilla as possible, but I want to actually play the game, not sit around waiting for kobolds to respawn only to have them tagged by some dude. It doesn't make the game harder, it makes the game un-freaking-playable.
I have a level 10 druid that took me 8 HOURS to get to; that's insane! I didn't get enough XP from the early areas because I had to 5-man group all of the quests and when I finished all of the quests I was lvl 9 with no bars. I grinded all of level 9 just killing mobs. Im in Darkshore right now as a level 10, and there are still so many people that I get maybe 1 quest mob every 2 minutes.
This isn't an exaggeration, this is a problem, and it has a simple answer: raise spawn rate. And for all of you with the blizzlike boner, Blizzard actually had to do this before. There were too many people at the launch of BC so they implemented a thing where mobs spawned more quickly the more people were in the area. I'm not even asking for something as complex as that, I just want like 3x respawn rate until like (and I'm ballparking here)... Tuesday? I love vanilla WoW, I'm getting a bunch of my friends to play this server. The work the Nostalrius staff has done is phenomenal and besides the shitty shitty spawn rate, this is the best vanilla server I've played on, and I've played on a lot of them.
