First i love the content of legion.
I'm a PvE raider and what i like in WoW is:
*raiding
*optimizing my char
*rank and improving myself
What I'm starting to really hate about this extension is simple : you can't optimize your char for all the 3 specs (with a reasonable game time).
And even if you try to focus on a single spec, you can't optimize it because of the legendary system.
Before Legion, having 3 dps spec was something nice : you could easily play 2 specs during the same raid tier.
The buff/nerf of a spec wasn't the end of the world : you switched spec, learned a new gameplay, liked or didn't like it but well every lock were in the same boat.
One spec was good in ST, one spec in AoE : let's play both to optimize yourself.
Legion :
*you need to invest time in a spec to farm AP.
*you need time and luck to farm legendary for a spec.
*instead of a single weapon for all the spec you now needs 3 drops for a spec (not even talking about bis stats, bis relics, procs).
It's creating frustration.
At one point you are gonna choose a "main" spec, in which you are gonna invest time.
*it's the best spec (there is always one) : nice !
*it's not the best but close to the best : mkay
*it's the worst spec : f*** it, you get frustrated because you invested time an sweat to be least efficient than players who invested less.
At each buff/nerf/rework starts the same thing, some lock are gonna be happy.
yeah my spec is good or i'm gonna be useless
And it's even worst for the legendary systems :
At least 3/4 of the reaction people have when receiving a legendary is : "oh god no ! Not this one !"
With the same spec : buff one legendary which become the bis or nerf a bis legendary (making another one the bis) :
*people getting buffed are gonna be happy
*people getting nerfed are gonna be frustrated
Example :
I don't have feretory of souls, it's already one of the best legendary for destru (it's good in all situation and gonna be better with 4P).
It's getting buffed.
Random lock got it, he is super happy ! "Yeah i'm getting buffed !"
My first reaction : f*** me, other lock with it are gonna be better.
Second reaction : i hope it's gonna be my next legendary and not the RoF ring, ppppppllllllzzzzzz ...
In other extension : you knew that at the end of a tier you were gonna have the bis or at least close to the bis of all you specs
In Legion :
you know that you won't have all the legendary, even for your specs !
(most people got around 4 legendary / maybe 5).
You know that when they are gonna add time consuming content (AP), you won't be able to have 2 optimized specs.
What is even more stupid : the best way to have the best optimized char is to create a reroll of the the same class/spec until you have the perfect legendary drop...
PS :
*If we had only a single dps spec, you choose it and hope to have the bis leg but there is nothing you can do about it.
*Spec can't be balanced : they have never been and never will be.
