If you're doing this online go down to ground level.... and play there.
YOU'RE MAD SAYS EVERYONE...
You're mad to stay at height, I'd say... Why??
Because if you go down, you're reducing your opponents advantage over other team mates that will arrive on the scene. You do not have advantage anyway, so by going down, your opponent now has to look over their shoulder, distracting their attention from you.
This has a big psychological impact making your opponent impatient and prone to making mistakes, which you can take advantage of..
Of course if more of their mates arrive .. you're in the poo
Take your chances..
