I disagree with your Overlord PvP skill build a small amount as well but any changes I would make are simply opinion, making yours nothing less than optimal.
The Savage PvP build however has some misplaced SP and is lacking 1 essential thing.
- Most importantly, every single Savage PvP build needs to have level 3 Aerial Kick to hit fallen enemies. This is a must.
-There is no use for CON in PvP unless you are using HP pots to heal the gap that the buff gives you at the beginning of each round (you're most likely not ).
-Nozzle Tuning is very important, in my opinion, considering how often a Savage uses Rocket Punch and how important M.Speed debuffs are to PvP.
-Somersault Kick, Relaunch, and even Mega Drill Drive are only useful if you plan on going swag-mode and using flashy noob skills to do fancy combos. The typical PvP build does not require these, and the SP could potentially be put to better use by investing in Stance if you plan on doing any type of naked or low gear/weapon PvP. Somersault Kick can be replaced by Air Combo Launch and Relaunch can be replaced by using Rolling Stinger followed by Air Combo Launch. Mega Drill Drive is simply a damage filler, and it usually bugs...only hitting once or twice.
Here is my recommended PvP build for Savage; level 5 Nozzle Tuning isn't necessary, but is one of the better options for you to be using your leftover SP on.
Now, if you're into using nab skills for interesting skill chains, here would be the build best suited for you:
