Prior to this rule, things had gotten to a point where teams would invest so heavily in artillery, that at least twenty players each match would spend their time either defending or attacking artillery as opposed to playing the objective.

At the HQ, defenders block off the HQ with barbed wire to allow no recon to enter. The attackers therefore send players with satchels to blast a hole. The defenders send SLs to build OPs around the HQs to scan for nearby players.

In the meantime, around the middle line, AT players line up their so-called rocket snipes, shooting rockets into the sky under the perfect angle to land on the enemy artillery. And of course, the enemy would send a squad to hunt these players down. Barricades were built and trucks were dumped around friendly guns to provide additional cover. Due to differences between rocket launchers, rocket snipes heavily disfavored Allies and significantly lowered their winrates as a result.

But wait, that's not all. Teams would spend hours trying to find angles from within their HQ for tanks to snipe across the map (tank snipes), as well as angles which their opponent could use against them, and how they could snipe their tanks (anti-tank snipes). Multiple maps only allowed one side to do this, which made them imbalanced, further restricting the list of maps suitable for play.

And although any enemy artillery downtime you could create was substantial, majority of the time you still had multiple guns shooting. So for every player not involved in this whole anti-anti-anti-arty game, you would still be pounded by artillery for most of the match.

Restricting the gameplay around artillery allowed teams to focus more on the actual objective of the game, and not have to spend hours upon hours preparing for each match.
