well , if you play like that it's your problem. 
anyways ....it has leaning , (oh but you surely will say in cs leaning doesn't matter...) , slow paced (but you surely will say cs doesn't need to be slow cuz you dead). 
seriously , tell me which fps is tactical for you so we can stop here.
oh , i see rogue spear is the only fps you played.....yes it's tactical but if you never played other tactical shooter you shouldn't even want to discuss about other games.
I play in the way that's most efficient in all games. Running and gunning works the best in Insurgency (and red dot sight makes ADS useless in most cases), and I stopped playing it because I was raping too hard and barely doing anything impressive skill-wise. 
Insurgency is a lot faster paced than CS. 
Arma can be tactical, Rainbow sixes at and before Raven Shield are tactical. 
"Rogue spear is the only FPS you played", wat? I mean.. not only do you have to fail at reading what I wrote when I wrote about Rogue Spear, but you also have to like... what? I've been talking about CS and Insurgency in this thread, haven't I?
