Yo, im leveling a sentinal using the hammer throw skill. Currently level 55. Was doing good damage and thw skill was at level 20. I decided to try a different build in the skill tree. Starting back at level 1 with the skill i cannot kill a thing. Its taking 4-5 minutes to kill a pack. Im having to go to areas a lot lower than my level where i can kill mobs to level the skill back up. It seems a bit dumb to me and feels way too long for a skill respec.
Respeccing of single nodes in the skill tree is in the works.
Thanks for that info mate.
