In my experience skill tree doesnt do that much - clear it does for the example if you compare a blood young one with a 1 year old player , but thats nearly the same in all other games - through the tome possibility.
If (balance) changes are going to come online(yes they will) than its also the same as a lvl 60 rougue in wow got nerfed after months of imbaness.
The only way to get rid of such problem could be a moba style attitude which i dont like to see in this l game (all the same all the time)
PS: i dont really follow the whole thread, but i am drunken and want to spit out my two cents xD cheers. Ftw!
