I voted for 'leave it alone'.
There's quite enough argument generated by 'Spit II/not Spit II' and now 'E4/not E4', without the server dictating loadouts.
If we take this to it's end point, so that all machine guns have ball ammo only and no cannons are allowed, what's next?
The server dictates fuel load I presume, so that everyone takes off with full tanks?
The bombers only get a certain bomb loadout?
I know I'm exaggerating here, but I have problems with being dictated to by server rules restricting what's available in the game.
If it's there, let's use it (albeit limited with the Spit II and also E4 in my view). It's part and parcel of 'playing the game', or 'simulating reality' (whichever), so if an individual's skill with loadout management gives him an advantage, so be it. That's as it should be.
Edit: Krups, your link goes to the main page for me, where is the discussion? Cheers.
