Caveat. These thoughts only concern PvM.
Ive been thinking about this for some time but with the crat nano changes its finally crystalised.
FC doesnt want us (any profession) to have a toolset.
Ok, what i mean by this is they dont seem to want us to have the ability to use our toolset to affect the challenge of encounters, the crat init debuffs are a classic example of this (perhaps they are OP but they are not so much being nerfed as taken away) but to name some more: Rooting to avoid fear in Texx/12 man, boss mezz to control CC-resistant adds (the 60 sec cooldown and terminate on death will see to that), bosses warping us to them with unremovable roots, Shades in collector that warp back to prevent mezz/root/snare control and the forthcoming 'cooldown added to just about everything' which makes sense in pvp but in pvm amounts to a massive nerf.
Ok now about the toolset, just look at recent encounters like The collector. Our CC toolset is thrown out the window in favor of making us the the kick we are given for that instance only. DB1 only way to remove debuffs is to run to a pillar. DB2 must kill towers/jump onto cloud. Dreadlochs, adds are CC immune and can only be boss mezzed (a nano which Means revealed his contempt for some patches ago) or killed and Albtraum, bosses (and some mobs) proc debuffs on you with no resist or remove possible.
My point here is in all these cases (and in others) FC is taking out toolset and preventing us from using it, making us do these encounters in the way they decide they must be done and punishing any innovation with a smug little 'fixed several exploits' in the next patch. Excuse me but i thought innovation, tactics and clever ways of using our toolset was what challenge was all about. I'm not talking about situations where people have found a way of making a mob defenseless so it was easy to kill, i mean situations where a problem was overcome not in the way FC expected it to be so FC stamped on that method of solving it.
It's starting to seem to me that the rebalance is going to end up neutering everyones toolset so things can only be done the way FC decides they will be done and all innovation and cleverness will be replaced by mediocrity.
What i would like to see is FC trying to work more within the framework we have and give us mobs/instances/encounters that we can (and perhaps) must use our toolsets on instead of nerfing them and creating artifical challenges with artifical solutions
