I like the simplification of the traits to just a single point however you have made it so much harder for me to enjoy playing a new character. I was at level 52 with a warrior I have made for WvW roaming and i had tier 2 set up so this was still viable even when upleveled. With the new trait system I lost all my tier 2 traits and have been unable to get back to the same stats as i was even now that i am level 70. On top of that i lost out on 1 gold i spent when i turned level 40.
I am really enjoying most of the update but this makes doing anything with a low level character now impossible. I cannot see any level 80 players wanting to run dungeons or WvW with lower levels anymore. I certainly wont be going through the grind of leveling up another character after this one as it is just too painful.
