Is there a right or wrong style of play? No not really... You pretty well have covered all the styles of play Dean and it has been an interesting read but there is no reason to critisize any certain style. Yes, we all hate being killed by campers or such but it makes killing them all the more fun.
Myself I dont think i fit any style of play. I usually let the map dictate what style i will play. I usually patrol a certain area and use the maps features to my advantage. If I need to run and gun so be it, its not my first choice and there are better players at it like Artie & Nick but i like to think Im pretty adept at it.
I guess its a hybrid of the four. I may not win ever map but Im happy to be close to the top with a very good ratio... Above all i do give Kudo's to the guys I play with. Its hard to beat Nick,Artie or Dawgy at run/gun. Laz, Pain & Mike are very simular to myself and thats hard to compete with. Then u have players like Ferret & Spanky that rarely use thier weapon and your either bashed or find yuorself dead by grenade... Thats a tallent on its own. There are so many players that fall between these styles as well like Rock, Van, Gom or Bart that any given day can dominate along with the many others I dont have time to mention..
Of course this is for COD2 but I have to give my props to everyone that plays on our servers. Somedays any given player can piss me off but its only becuase they can get the best of me at that time.. and at the end of the day I respect that and whatever style they choose.. Kudo's Peeps!
