Lucifer, please re-read the text you keep quoting. As you say, it is quite clear. It says that debuffs are being put on the back burner until after version 2.0 is released. Let's read it again:
Notice the word "before." I have no plans of further explaining their use of this word before I go home (however, I fully intend to explain again after I get home, as I fear you will still not get it).Also, there are no paralyze/poison/silence/absorb/slow and there aren't any plans to implement them before the launch of version 2.0. However, as we move forward, if it becomes absolutely necessary to utilize them, we will look into it.
Additionally, your issue is that you are losing what you consider a THM to be. It is your loss of identity that you are seemingly upset about, not the overall effect on the game. You see yourself as an excellent debuffer, and you are losing that ability after the patch. You are left with a few choices to address this challenge: You can adjust and become an excellent nuker, you can switch classes into something that you feel would give you back your identity, or you can quit the game until they release a class that has an ability list which you feel suits your identity. Whichever choice you make, the majority of the community will be playing a much more satisfying game.
