Gotta agree with Superman on the fact that things that get changed aren't what will help this game. But, your game, your choice.
Why do you think this game is still alive even though it's nowhere near the same quality visually as most games these days? It's not because it's easy on computers, cause it lags more players than a lot of visually-appealing games. So, if people are staying knowing there's prettier games out there, why is it? Well that's pretty obvious dontcha think? It's because the gameplay is so fun!
Now lets look at why players don't stay... would you really suggest it's because they "struggled to get good" ? (I have never just been amazing off the start of any game) Or is it because DP (especially with default textures on download), is ugly, gives bad FPS, and some more criticisms.
So if changing stuff that keeps your current community around doesn't seem logical, does it? Shouldn't you do stuff to keep or attract new players? Jumping is the main aspect that seperates good and bad players, anyone can spray in a 1hitkill game. By making jumping easy, you make the current competitive scene die a little more, and it still doesn't attract new players. Now this being said, I haven't watched any demo's but somebody explained the c1 jump to me, and I'm judging a lot of it off posts I've read.
What's important? Attracting people? Or changing it how you see fit? It's your game, but you don't play a lot and if you truly want to see it grow, you should take the opinions of those who actively play. (featurevotes)
