In my opinion, it's Okay.
Because Demolition Skill in this update has a lot less cooldown compare to the last patch.
On the other hand, Deadly Smash has increased the damage and also cooldown(however, doesn't long as much as Demolition from the last pacth).
(you may can use Demolition,Deadly Smash,Demolition when you are at higher level. )
If you notice, Deadly Bloow has increase cooldown too.
Area destruction seems to haves less damage a bit but also have less cooldown which you may can spam it if you have not much attack speed.
Also, all skill seem to have less asp to perform faster.
