Genuine question.

I always wonder why (especially the pros) use cross-shaped crosshairs as opposed to a single dot. Tarik is like the only semi-pro I can think of who uses a dot.

Perhaps it's just preference, but I was wondering if there's any legit reason behind it outside of preference? Personally, I easy go 30 frag games using just a dot but the second I use anything even moderately different I int all game.

​

Thanks.
