Actually the paragon system might be exactly what you asked for the talent trees.
Online you can already find talent calculators which even show the structure and layout of a paragon tree. It is even devided in specializations like “wind” “earth” “wolf” “bear” “shapeshifting” which all have there own skilltree there.
If i remember correctly in some dev blog it said that the paragon system will allow you to alter your skills.
So with this i would assume the “skilltree” of the beta is just as a way to select the skills you want to use on your build and the paragon system actually giving you the tools to specialize. As some say, the paragon system looks like it is capped.
Of course there is the question how long it will take to unlock points there?
So far in the beta the leveling was super fast but the exp rates might be higher in beta then on release. Reaching lvl 25 in 3-4 hours…So the Paragon levels might just balance out the super fast leveling. At least for me it would be no difference spending lets say 48 hours playtime to reach maxlevel end unlocking all my skilltree or if i have to spend 8 hours reaching lvl 8 + 40 hours unlocking all points on the paragon skilltree. In the end it could be the same time investment
So you might want to look a bit more into the paragon system before wanting it removed just on speculations.
