Replacing spawn weapons

I'm mostly in favor of the idea suggested by Samual, but the problem is that we're throwing too many functions for one weapon (that is combining laser, shotgun and melee into one weapon) which will make balancing the weapon harder and i thought we were trying to make it simple, and since many want the juggling aspect of the laser plus the laser being the primary instead of secondary and also many are fond of shotgun as a finishing weapon I have a suggestion to make:

I say why rock the boat, lets combine laser and shotgun into one weapon (new model perhaps) with primary being laser and secondary being a burst of shotgun (I heard in nexuiz days when someone respawned many were using laser+triple shotgun burst combo when pressing the secondary laser key, so this is ur nexuiz reference )
Then we are left with melee attack, i agree as some have already mentioned that a melee for every weapon is ideal in this situation and many cod bf games have this function (perhaps use the vacated bind for the shotgun as a melee attack for every weapon).
