First off as a new member to not only Counter Strike (only had it for about a month or 2) and the Steam Gamer community some of these rules are fine they way they are as they are not hard to pick-up and easy to follow. Also I definitely agree with Motd needing some improvements for some more rules being displayed seeing as some I didn't know some rules even existed because they weren't displayed.
While some, especially warning shots along with others, definitely need to be pointed out a bit more as they are taken advantage of or are ignored. People tend to use warning shots only if the see the pistol holstered and nothing else, even after they have been explained the rules time and time again.
Also I like the Jihad Bomb and anyone who has seen my in game knows that. Obviously it is a pain to have to open up console to buy or bind the keys for bomb and sometimes I have been freekilled for this as I am a slow typist and they saw it as disobeying the orders even if I have said "Don't kill me I am typing"
Also as for the maps I usually see them same maps time and time again because people spam the 1 button instead of actually voting. I'm not sure if can do anything about it but I'm just saying it gets kind of annyoing.
Well I hope to see you in game so I can kill you...Bye =)
