TBC blackrock quest - AV and AB
So as mentioned in the topic, the issue here is with the karazhan quest chain, specifically the AV and AB quests. It has a few core issues :
1. It is not based on your skill and you have no control of the outcome. You can't solo carry 39 people, or even 35 if you premade. The Mine NPC'S have 3k hp, which is 1 shot for any rogues. After a few kills, they bug out thus leaving you stranded. There is no actual way to defend them. If you invest people in the mines, you will just straight up lose the game.
2. Second issue being griefers. Onyxia players are catching up with what quests blackrock has and every time you go to AV there will be a few rogues that do nothing else but sit at the mines and camp to intentionally grief you.
3. AB quest - basically the same as point number 1. Has absolutely nothing to do with your personal competence, as there 14 other ppl in the battleground that you are reliant on.
Border line, these 2 quests should be replaced, something with more general, like winning something and not being dependant on certain objectives that can be griefed by other players.
