I don't get what the big deal is, you will still receive more than enough ability points to skill your character with tenebrium weapons...
It makes the weapon skills completely pointless after the 2nd act. At the very least, that's bad game design.
Anyway, you can redistribute your attribute/ability/trait points in the homestead if it bothers you.
Respecing also makes you forget every ability you learned, so you need to track them down and buy them again.
The weapon skills exist to make certain characters feel different from other characters. My 2-h warrior is great with 2-handers, but sucks with 1-handers.
Well Tenebrium throws all that out the window.
