Snap kick = 20 frame kick.
What I dont like about it = It limits all creativity, In other words it makes the game borring. Why? (already said it) Its like playing rock paper scissors, there are no variations, you already know every possible reaction to that action (snap kick) so snap kicker wins in the first 20 frames or he gets anticipated and looses.(can you see a relation with snap kicks and rage quits? (Optional: snap vs snap)). This game has so many variations, 4 options per joint, 20 joints, 4^20 = 1,099,511,627,776 possible configurations per turn. So snaps reduce that to almost nothing.
Its a matter of perspective, if you only care about winning then my point might not be valid for you. (subjective)

Do I think its bad? = No. Its just a move, it can even be justified in some situations. Even if I dont like it, I still dont think its bad. Why? well... look at the tk ranking list, I've been #1 for months. Does that means I'm very good? No. It means I'm always ready to counter rush openers such as "snap kicks".

But it seems that snap kicks are not the problem. The problem is the raging about snaps or lets get to the point... It looks like the problem is that you care to much about what other people say/think (rage talk when you snap) so the conflict is Snap-rage, action-reaction, such as this thread.

My advise would be: dont care at all. Let the loosers talk. Snap as many fags as you can ;)
