Hey folks! I'm leveling a new shadow. Cananyone recommend a pve leveling build? Where should I spend the first 10 points? Thanks for your opinions!

Hi folks! Rerolled my vanguard trooper as a commando and want to try gunnery spec. Is there a recommended build progression? I'm basically trying to figure out where to put points first. Thanks for your opinions!

Ok stupid question: Which size did you go with? I rolled a toon at the average height (2 I think) And he seems very puny with the BFG. If I roll a bigger toon, like size 3, does the gun just scale up anyway? Is the size thing a big deal in PVP? Thanks for your opinions!
