Hi,
This happened to me long time ago,
now I can share it with you.
If it is a repost, I'm sorry ( I used search ).
You can explore BG before it starts if you have lag.
It happened to me as I had shitty ISP long time ago.
I could reach middle AV map before fight starts. (happened once) - it's all about gate spawn that is delayed (sorry I didnt explained in the first place!
now i thought that you could make artificial lag, with 3rd party soft to do it again.
Dunno if it will work. will try it later.
share your thoughts on that.
