I don't understand this type of argument. Yeah, Quake 2 takes skill to be good. TF2 also takes skill to be good. Are you trying to say a skilled Quake 2 player is "better" than a skilled TF2 player? You can't make that kind of argument - it has no solid ground or evidence because you're comparing two different FPS and just shouting about one being better than the other.
Yup, you're right, LMCTF is nothing like TF2. That doesn't mean it's harder; one isn't harder than the other, it's an impossible comparison.
I can show you a Youtube video of a TF2 game too and try to show it off as being "better" if you want.
"TF2 sucks, period", isn't a valid argument about one being more skilled than the other. It just means you dislike its' gameplay.
"kthx"
