Yes, Tenebrium isn't really resisted by much, and it tends to be the lowest resistance on things that do resist it. That still sounds more like a case of "enemy resistance tweaking needed" to me, but that is a point.
A much-pointed out problem with respecs is that you lose all your skills and don't get them back as skillbooks. Having to go around tracking them all down again is an unnecessary annoyance, and that's even if the game didn't have one-time-only skillbooks which can be lost forever through re-specing.
Getting Tenebrium 4 or more is still a waste of points. Because you're not getting a more powerful weapon. Crafting a weapon with a Ten. bar requires Ten. 3, but you get the same result from crafting with Ten 3, 4 and 5. Never seen a Ten. 4 or 5 weapon drop, either.
