I guess if you are allways using the situation at your advantage, fine tuning your char, and getting tons of kills by doing "dumb" and easy stuff, many elite players will expect you to add a little danger for yourself and make things more spicy. I will usually rage at someone using EZ mode tactics for too long, as it is not fair. If everyone was continuously exploiting everything they could to win every round, the overall atmosphere and sympathy among the community would suffer greatly.
That is how I perceive fun for "elite players". If you score kills too easily by using unfair tactics, then add something spicy to have fun. Sadly some people are so much rageing for their deaths they enjoy killing people by unfair means all day long.
