Why do people only play Lost Planet with Rockets

This game is so much fun with STANDARD weapons but everyone plays rockets only. I remember this is why i stopped playing this game back in the day. Its fun for about 2 minutes and it turns the game into a dull bore fest, roll around, shoot rockets, takes no thought whatsoever, also makes VS units not even worth getting in because 2 rockets and you're done. Play the game how it was meant to be played with standard weapons
