I'm personally not a fan of the system in place right now with Ts spawning in B site and Long A, and CTs spawning in T spawn and A site... it seems like players just pick their team to play from those spots, IE people joining T to be able to awp out of pit. I much prefer the spawning system in the HG d2dm, where players spawn wherever their teammates are congregated, that way they can all be in raid parties and take certain sites and hold them, which is really fun. In contrast, the wl spawning system makes it so that when you push to a spawning location, spawn killing is easy and holding that site is impossible, making players play picks from far away instead.

EDIT: one more thing. The current spawn system makes the game really predictable, you know exactly where your enemies will come from...
