Considering Kronos apparently bungled its betatest completely and had to completely shut down after four hours, they'd have to pull of some kind of a miracle to rescue themselves or Nost has to fuck-up massively.
Kek, a crash on Nost moment ago, every single character lost the boots they were wearing.
Yeah and everyone got them back.
mobs of level 5 dropping 20+ blues and greens
Never happened to me though I've heard it happened in the first two days. They fixed that in under 48 hours.
wrong pooling causing near zero resources to spawn or million at once within 5 yards
Never seen that happen and haven't heard anyone of complaining it being that bad.
quest connections (you can get quests in wrong order)
Never seen that happen or even heard of it happen.
patrols of mobs themselves (some don't, some got wrong routes causing a mess)
Never seen that either or heard of it. Every mob that I've looked for, I've found in the exact spot that old WoWhead comments say them to be. Some patrolling mobs were bugged at first, Forsaken Courier at Arathi for example never moved from its spawning location, though considering that Alliance camped that spot almost 24/7, he didn't have a chance to get anywhere anyway - but there is absolutely no evidence of wrong routes.
hp and damage and armor values
Only one I heard of were the warlocks Demon Skin buff and druids Bear form, which were fixed in the first week.
some basic AI database scripts (think of murloc using Backstab on your face without cooldown)
Mobs have always been able to backstab from any direction. Some mob ability cooldowns are wonky, most aren't.
in Deadmines when you kill boss, door opens and mobs are supposed to spawn by the entrance and walk to you. Well they spawn, they don't walk and when you attack them, you can kill them while they just wander around without a single response.
Nope, the patrol does reach you, I have no idea where you got that claim from. I've played Deadmines, Black Fathom Deeps, Razorfen Kraul, Scarlet Monastery (all wings), Razorfen Downs and Uldaman multiple times. The only bug I've personally encountered is the final door script in Uldaman, where you use the pedestal to active the elementals, not working. People have successfully done all 5-man instances and last night Molten Core was raided for the first time. There are occasional hiccups, but by-and-large, things work.
I think you're just repeating bullshit spread by Kronos fanboys or Redditors, combined with the hyperbolic crap that gets spammed on their forums all the time.
Oh and the rest of your analysis:
It causes situations where there is 50 people camping on a single mob spawn like in first day and even now when it's more spread out with any bad luck you might be going around for 30 minutes or more without single kill.
I started a nelf priestess 2 minutes after the server launched. The starting area had more than 200 nelfs in it. I immediately made a group of 5. Sure, we had to camp spawns like mad but sharing kills enabled us to get out of Shadowglen in about 2 hours. I made level 12 and got out of Teldrassil in about 8 or 9 hours. The only time I've gone without killing for 30 minutes is when I've been busy in AH.
Yeah, quest items can be a bitch to get at peak times when they aren't shared between party members but killing quests are piss easy to do and you can always find a group at the snap of your fingers. I know that a lot of people have grown accustomed to just soloing their MASSIVELY MULTIPLAYER games and Blizzard definitely made it extremely easy in WoW expansion by expansion and patch by patch. So you do need to unlearn all the bad habits of the last few years and get in to the custom of teaming up with other players. Helps tremendously with world PvP as well.
The only thing about the large population that worries me is the reputation grind at 60 which is going to be painful. But you know why it took me over three days to reply? Because I've been playing like mad and enjoying myself tremendously
Now personally I don't give a shit if you play on Nostalrius or not and whether you like it not, but don't just repeat half-truths or, worse, baseless claims willy-nilly. Save that for the Bioware thread.
