I updated those notes accordingly on Lacerate and F-Lightning.
Your "shielding in unimportant in pvp" comment on the Darkness tree makes you lose pvp credibility.
Lacerate is also useful as it tags people trying to cap stuff.
Shielding is unimportant in PvP. Critical hits (very common) prevent shielding from working. Non-weapon damage based attacks prevent shielding from working. You'll notice a survivability increase with a shield, but not nearly enough to offset the damage decrease in PvP in my opinion, except for purposes of Huttball running.
