I believe the OP's point was totally lost because of the way he spoke of things.
OP's initial post was somewhat offensive towards PvE warlocks by totally removing their say in the matter or simply making it feel like PvE has no regards towards the matter,regardless of the consequences it would impose the PvE warlock aspect if these changes were taken.
I will try to correct his statement, in the way he intended.
Affliction has been a core aspect of the warlock gameplay since times immemorial, though some stated that the OP wishes that other "viable" specs should be nerfed so that affliction should be changed or somewhat go back to the way it was , is not his actual intention.
What he meant was, affliction has gone through a paradigm shift, where the multi dot / mobility / tankish'ness playstyle is no longer existent, instead now our dots are somewhat weak ( in regards to the current evolution of damage in general) , and the previous amount of "pressure" that affliction could produce has been halved or more , with it's core power shifting in design towards malefic grasp this has significantly reduced the multidot pressure, since channeling is considered taboo in pvp due to many reasons, primarily involved in a certain psychological weakness where interruption of the shadow school would be demeaning , and secondly totally demolishing the mobility that was previously held by affliction.
Although many "old" warlocks have gotten used to the playstyle, this sudden change in mechanics simply feels weird, although it is refreshing ESPECIALLY in the PvE aspect, I do not think what the OP meant in regards of changes was implied in the way that it SHOULD be changed in that fashion, simply stated he wanted to say what he felt like affliction has lost and that he misses the previous playstyle, though his statement of change had drifted and his intention has gone amiss.
To conclude, the OP meant that he fears for the incoming nerfs to demo and that our only viable spec ( although strange) might be demolished , leaving us with half broken specs and truly impossible mechanics to deal with in high rated pvp, which was asked by a change or fix to affliction so that the spec could be played again with it's previous intention and power.
This does not mean that PvE affliction should be affected, he merely wanted the change to help PvP affliction without really touching the PvE aspect ( or so he thought with the changes he demanded), although those changes might not have had the intended ideal solution to the question at hand.
