I'm lvl 39 ATM, rank 26 valor, usually place #1-2 in PVP for damage done and medals received and an active participant in all PVP games, meaning I cap in Huttball, hold down objectives, etc.
I'm specc'd very similar to the Sniper's handbook's Engineer guide for levelling as I find it the easiest to level up with.
That being said, I cannot believe people who say they solo heroics their level as a Sniper. I find it hard to take down PVE Elite mobs my level for class quests (Quesh is a good example, Master Berrin Fraal owned me hardcore, Doctor Lokin couldn't keep up heals and I was down within seconds after stimming endurance and medpacking.
I'd like to think that I'm a good sniper, and have a solid rotation, but I still can't fathom people doing heroics without issue as they claim to do so on these forums.
Could someone shed some light for me? or even better, can anyone point me to an around my level video of a sniper soloing a heroic at their level?
