Ok, after looking at the replies and fooling around with alts some more, I finally realized something, the dirty fighting scoundrel is more versatile than my shadow or other toons. That versatility makes it harder to play because each setting calls for different strategies and tools. So I changed up my tactics to that of a range fighter that can use close combat to escape or finish a fight not stand toe to toe. I also started from range, when I could, from cover. Results, I got my highest score and most kills ever. (Guess those dots did more dmg than I thought!) I was surprised to notice no one attacking me while I was in cover as it is on my gunslinger. First I thought they were ignoring me because they know scoundrels don't do much dmg. Then I realized they were ignoring me because the saber wielders like to leap at you and they can't do that from crouch. Also I was afforded some protection from range by cover. This allowed me in certain instances to pump out the dmg. But this is a versatile class so that doesn't work in close quarters. For that, I am learning to stick and move. At 29, I don't try to takle someone in PVP by myself, although I just got a complete solo kill in Huttbal by disappearing and reappearing behind the target with a kick, shotgun, and slap.
What I've learned as a low level pvp dirty fighter:
1. Use crouch at range to make them come to you while you pump out dmg on multiple players
2. don't fight anyone at low level toe to toe. Help other using your cc and backblast
3. You are versatile use stealth strategically, not as your main strength
4. In close quarters stay mobile and keep the pressure on with multiple foes while assisting other classes.
5. You can heal.
Question: What counts as an "incapacitated" target? I have dirty kicked, blinded, and dotted plenty of people but I am still not able to use head shot. I have even been right behind them and its not showed up. How do you get it to pop?
