If you fire more than a certain number of ballistic weapon of the same kind within 0.5 second, you have to pay addition rounds as tax to alpha strike.
Take the 4 AC5 Cataphract that is ruining our current balance for example. You shouldn't fire more than 2 AC5s within 0.5 second as that would be OP. So if you really wanna boat that OP AC5s, we won't stop you from doing it, but if you fire 3 AC5s within 0.5 second, it will cost you 3 rounds + 1 more round as tax. If you fire 4 AC5s within 0.5 second, it will cost you 4 rounds + 2 rounds, therefore effectively limiting the alpha capability of the AC5 boat, while leaving loose restrictions in the mech lab.
Of course there are some crafty players out there who think "I'll just mix some AC5s with UAC5 to circumvent this mechanic". I've thought of that as well. UAC5 will be considered in the same family of AC5 in terms of alpha strike limitation, thus putting those 2 AC5 + UAC5 boat in check.
Here is the table of the alpha limitation:
Weapon family.....Can fire without tax...........ammo tax with each more weapon from the family
=========================================================================
AC2......................3.......................................1
=========================================================================
AC5/UAC5............2.......................................1
=========================================================================
AC10....................2.......................................2
=========================================================================
AC20/Gauss.........1.......................................3
