How to guess arty position?

Berbo: Apart from tracers, don't break fences, houses, trees etc. I remember players being countered when we had no tracers.
Taking "popular" positions and standing in center of the bush is not a good choice. If you want to be in cover stay Behind the bush, and in case of light/medium rush go directly in it.
Mines is the map where you can literally guess enemy's positions.
