Let me attempt to use different words to get my point accross;
Half-Life 2: Deathmatch University should not be your only stop in your quest to beccoming a better player and should be used as a tool only. It is a good resource for information but it needs to used in conjunction with a boot camp that should be used in conjunction with a powerful tool; Common Sense. “Boot Camp” can be as simple as pressing escape and studying your control’s. Walking, Running, Crouching, Sprinting, Aiming and Shooting are all basic movement teqniques every player should master on there own before they try and tackle more advanced multi-player feats of coordination like “bunny hoping” and “grav jumping”. The only way to truly master any teqnique is to do it over and over and over again and that can only be done with time. The end result of the U is players that lack the information and education to inteligently defeat there opponents on the battlefield provided by valve and lack the basic knowledge and skill to manipulate there character on the screen. Take a look how the military trains new rectruits. Everyone starts at the bottom and works there way up slowly getting educated on how the system and the world around them works until they are fully trained and profficient in every aspect of there job. Its called proffessionalism and the same logic can be applied to your game and every aspect of your life.
The “Rules” of the game are simple; Kill or be killed and use the tools given to you to the best of your ability and have fun. The original Half-Life DM was simply the multi-player function for a single player game and not stand alone. Again the rules were simple; Kill or be killed using the tools and teqniques you have mastered while playing the single player game. Half-Life 2: Deathmatch takes those same fundementals; use the tools and teqniques you learned in the single player game and apply them in the field against your friends.The logic behind that is to make sure you have the basic knowledge and skills to at least be able to function in the single player environment before you graduate to the more advanced concepts and movement teqniques in deathmatch. Left 4 Dead takes those same aspects of survival and the kill or be killed atmosphere of DM and the single player aspects of the half-life series and blends them all together. Communication, Coordination, Teamwork and common sense are essencial or you will fail. You don’t know how to play? Play the single player, learn how to move shoot and aim, and then try your luck in the field.The U seems to want to get players ready and interested in the CAL aspects of gameplay only. You have attemped and failed to turn deathmatch into a sport and tried to apply sportsman like behavior into a war zone and change the roots of deathmatch and coincidentaly seem to have lost track of what the game is about; Killing your friends and having fun in an environment with no rules.
