We shouldnt have to go 'Full' specs. The game was made so you can be fully customizable and still be viable provided your customization is legit and actually works. And by them taking away our 'Hybrids' they are taking away from customization thus the fun. nobody wants to run a run of the mill cookie cutter full spec and they need to deal with that by making the trees so they work with each other allowing for said customization.
you still have the freedom to customize your build. BW didnt take that away and are not tanking that away. what they dont want is for hybrid builds to out perform full builds. they especially dont want hybrid builds that end up performing better than any spec is intended to perform( like the PT hybrid on PTS right now ).
