Great! Lets be friends!

sorry but breaking range with mad dash to leap in again is great against assassin. Your goal in a 1v1 is to have a higher damage uptime than your opponent. If you can get your dot rotation off, mad dash into a charge you have given yourself much more uptime than the assassin. I am not saying, hey run around while an assassin hits you in the back...

Jugg has much better DCDs than a Sin, so you best bet is to know when they are going to vanish and do your own tactical swap / channel hatred immediately. Use your CC when you are able to do your biggest damage and break range as much as possible since you are doing dot damage as Veng. It is an uphill battle if you are not Immortal, but the fight is pretty close if you are both playing correctly and countering eachothers DCDs. The hard thing to overcome is if the Sin is good and stops hitting you immediately when you pop Enraged Defense.

all of my friends that are ranged are making so much more valor in ilum than me right now, I am probably either going to reroll or quit till they have a solution for this. Basically as a melee character your dollar is worth a lot less than the dollar of a ranged player

Since you don't earn valor based off of your group, melee classes get far less valor than ranged classes. I would say easily 90 percent less than ranged classes because, as melee you simply just don't get valor for the kills of your group. What this means is when republic and empire have huge numbers facing off and all the ranged people are getting kills you are left with nothing. If you do rush in to get a kill and maybe earn a little bit of valor, you are instantly killed. How is it fair that you are rewarded so much worse just for picking melee?
