Most Recent Update Related to Survival Mode NOT Versus Mod
Valve does not care about the survival community in its L4D2 game, only the versus mod players. It's quite evident in its most recent update.
The new updates are not balanced for the well-being of gamers who play survival mod. Yes it's suppose to be difficult to get high times, but not headache impossible like the most recent update released.
Strategies which promoted cooperation with team mates and hardwork have been supplanted by unrealistic expectation for the gamer in the most recent update. An artful strategy which required discipline and teamwork, such as the classic hold position in the Atrium Mall map is no longer viable as valve released worse and worse updates.
If players are going to cheat and get a high time, they'll find someway to do it through mods or glitches. Whatever. We can just see their scores in their survival stats if they have a public profile. It's arbitrary to prevent glitching or having new patches for this 4 year old game and punish players who have been loyal for years.
Valve is releasing "fixes" to something that wasn't broken. While there are some meaningful updates that should be addressed, affecting the A.I. and survival community is not constructive. For instance, No Mercy Roof Top is near impossible to get 10 minutes on for even really good players.
I don't expect a reply because from what i've been hearing from most of the best l4d2 survival players, valve genunely does not care about its fans, just their money.
