Played sharpshooter since the beginning, actually changed to dirty fighter few weeks ago.
Answers based on sharpshooter spec.
1. How do you think your Gunslinger spec is perceived by other classes?
PVP: High damage spec but pretty easy to kill. Low mobility.
PVE: Good damage with excellent burst. Challenging spec to play efficiently.
2. How do you perceive your own spec?
On ability level sharpshooter is a fun class to play, but the last update hit sharpshooter too hard. Sharpshooter really shone with stacked armor debuffs and in situations that needed high burst. Now one them is gone and the other took a significant hit. Currently can't really justify keeping my favorite spec.
