Not all, in fact only a few people of the entire gaming community hates campers and tubers. Remember, for every 1 person posting on public forums, there at least 10 people playing the game without checking their local gaming communities. They play with the tube, they camp, they don't care about posting on the net. Its just one of those things. In the past everyone had to play on public servers and had to endure gameplay that didn't appeal to them. Nowadays however, you can run your own server and enforce rules to accommodate your taste. One day I will have a server where we can have tea and biscuits, discussing the later works of Hemingway.
Having said that, its very funny to see clans break their own rules. On a certain moshpit server there is a clearly stated rule about spawn killing. Now I personally don't care, preventing people from spawning is another way of preventing them from achieving the objectives, however to ensure "fair" gameplay let them spawn at least. Anyway, seems that on this server the rule only applies to non-clan members, the clan members regularly enters the spawn area mowing down anything that moves.
Its these little things in life that makes it so interesting.
