I'm going to be playing a Sniper/Marksman.  I've seen the very nifty toolkit that's up to plan for how to distribute your skills and the recommendations people have for various builds.  My question is; what order to I take these in?  Do I want to focus only on the Marksman tree to get to the top of that as quickly as possible, or build more slowly getting all the lower-rank skills for all three trees (that are recommended to be taken in the first place) then go up a tier, etc?

For reference, I'm looking to use the very highly rated build here: http://db.darthhater.com/skill_calc/imperial_agent/sniper/#::f2ef9ef8efe3fefe10f13df4ef

Edit: clarifying further, this is intended for leveling and PvE play.

not sure if im doing it right, but i generally get the low tier ones first such as more energy and higher crit before beginning on the marksman tree

It's a preference call. Personally I went up the MM tree first as I wanted to get Followthrough ASAP.

talking to people in vent they suggested go straight for max marksman then get the others.
