whats graw 2 like then?

Hey i used to be a really competitive gamer back in the day playing socom 2 and 3. i checked this game out, and it seems quite similiar to it. My main concern is improving my rank and clans and stuff, as i am really competitive. the gameplay of the game seems to be WAYYY better than socom, but that can only go so far without the ranking system for me. What im trying to say is,

1. how does the ranking system work in this game?

2. the clan system?

3. do you have medals, or icons to indicate rank in game?

4. how do u join games? is it like a server u can scroll and select and join, or is it random matchups through searching( u know like halo, and most xbox games.)

THANKS

Anything really stand out? i want a good bang for my buck. i like action adventure, rpgs, multiplayer group games.
