People are fighting in the forums about the current state of WoW questing.
Some people,
who have played the content repeatedly and probably have seen every zone from every angle, are annoyed that Blizzard gives mobs more health. Even if it takes about the same time to get to the cap... even if you can skip two expansions, it's a bad change for them.
Then there is the other faction of players. The ones
who enjoy the journey more than the endgame. Some of them might have only few characters on level cap, others just love to read and live the stories in the Warcraft world again. They are happy with the changes, because 1hitting mobs just breaks immersion considerably.
Who is right. I say: both
I think it's not a good idea that Blizzard tries to find a balance - how much health do the mobs get. How much damage they do. In the end they won't help either faction. Why?
...because the first faction - the people who know the content in and out and have done it too often, they basically don't want to do it AGAIN. 1shotting mobs makes it easier for them, but in the end it's just a compromise. With more levels in future expansion, it gets more annoying and more annoying to level the next character.
My solution would be quite radical. I would give both factions what they REALLY want.
1.) The Questers: give them a decent journey. Give them the experience they had with vanilla in terms of difficulty. Why do you think people want the classic servers back? Let them experience it here.
2.) The Veterans who've seen everything: give them free (yes free, or through the achievementpoint system earned) character boosts. At least a boost to the beginning of the latest expansion. Haven't they earned it, spending years in the game?
I think it would be a win-win situation.
