Because I dont do mega pulls of 50 mobs early on in the season for a +5…
I go pull by pull. Pack by pack. 2 or 3 mobs at a time. The only difference is how long you take to figure all that out. Some people only need to see it ONCE cause mobs, in the end, always do the same thing. Swirlies, frontals, casts… its just a different iteratoin of the same 5 mechanics. <— veteran players go here.
Others need a couple of +5s pack by pack to figure it out. And that is the “new player experience”. And its fine. <— new players go here.
And everyone in between. Because each time you complete a dungeon, you add to your “XP” bag that experience. Its not like veteran players were born with a wow account you know… 
Also: New players have bigger challanges than M+. For me, its incredible that a new player sticks arround the absolutely horrible, attorcious experience from level 1 to level 70.
Or because they refuse to pay attention and are at a level they should not be in. And for the record, its perfectly fine if a player just wants to log in to ZugZug and relax. And blizzard allows that, and gives people content to do that.
What is not OK is for those same people that want a ZugZug experience, to whine about not being able to do it on higher keys when its not possible anymore.
Like me. I get tired of high keys too eventually. I log into my warrior and I do +2 or +5 to do preciselly that: ZugZug and not think about anything. But you will never see me bricking people’s 10s because I want to ZugZug.
We will see about this. We cant continue to have the same discourse we had in DF because its not the same situation.
I think blizzard realized already their mistake in S1. That the squish did not work. So they did the obvious: Nerf M+.
By how much? That is what I dont know.
Basically. In S1, an “old +12” was a new “+2”. And that was ~ true. Today? After the nerfs? How much would an old “+10” be in M+ today? I dont know. I do know that its less than before.
What I do know is that high keys became harder. That’s for sure. By virtue of simply having the -15s death timer, and an exponentially higher % difficulty increase per key level. Plus all the hidden changes like the spell quew and kick changes in TWW.
So I can confortably say that a +18 today, is harder than a +28 in DF. But that dosent mean that a +8 today is as hard as a +18 in DF.
You tell me. What do you think?
