The majority of my time is spent as an Engineering Sniper in PvP.
1. How do you think your Sniper spec is perceived by other classes?
Underrated, Engineering is definitely the least popular sniper spec and it's utility is not that well known outside of those who play the spec. When I explain the spec to others they are often surprised at it's capabilities. Those who know about plasma probe interrupting objective capping often think it's overpowered.
2. How do you perceive your own spec?
Very powerful ranged dps with some excellent utility. I would go so far as saying that engineering sniper is the best ranged dps to bring to organized group PvP, as it has more CC, more burst damage, more utility, and more AoE pressure damage than Sorcerers and Mercenaries.
