So every few patches I download the test server, to test out some tier 10s and see what I want to grind on my live account etc, but another function I use the test for is to play clickers. The reason not being that I enjoy it, I despise it, I play arty on the test server as a way of improving my arty avoidance skills on live. I get to see what the limitations are in terms of various map positions and the kind of shots they allow for, along with what maneuvers are most difficult to predict, which arty is most effective, exactly how long their reloads are, etc. I highly recommend people do this,
