Brogan I'm not sure if it's you that played on my Pact team on hammerhead earlier this evening, but the player had the same name as you. The NATO player had 8 MLRS which destroyed most of my force near the start of the game - for some reason you then followed me and lost all of your forces, which then caused you to rage quit. I actually had sent sneaky infantry to the MLRS base and despite the defences I managed to kill them all, and then went on to kill several commands. So after a terrible start we won the game despite the heavy losses to rockets at the start. They would have had a far better chance if that player had not deployed 8 MLRS, despite the early success it gave them.
To be fair, I think they would have had a better chance had they been more skilled. Using artillery is valid strategy that can work, although whether it works depends on the skills of the player involved. Also, it was a 3v3 and a player going all-out arty is probably less warranted than in a 4v4, and sacrifices front line strength.
I have seen a team with an MLRS player win time and again, even if I have also seen it lose. Surely you must have too? Being successful something around 50% of the time means its a valid strategy.
And others agree with me. from the unofficial strategy guide viewtopic.php?f=12&t=1371
"Artillery Spam: In a team game, if one player decides to build a lot of (spam) artillery, the shell density can be increased to a point where strategic area fire becomes annoyingly effective, and any concentrations of troops are at risk if they enemy knows your general area. You need to position and reposition your troops to mitigate the risk of random shell impact, prevent them from knowing where your concentrations are, and know when your force has been spotted and reposition before the hell starts to rain.
If you can withstand the bombardment, or make him waste his shells on empty ground the enemy will exhaust their supplies very quickly, strategic artillery can be effective in team games of 3v3 or more, where one player can dedicate their assets to their artillery, supplies, and the defense of the artillery."
