Try it! Or, if you're like some people, don't try it and complain about it anyways.

Installation instructions: Place .zip in your My documents/my games/GPG/FA/Mods folder. That's it.
Edit: Version 2 is now up. The shots now cluster around the target, rather than behind it, mercies also have 100 hp (from 10) and have a turn rate of 1.0 (from 0.6). This should even them out a bit.
Also, I ran some quick tests. This is how the break-out worked:
10 mercs did about 9500 damage to an acu
1 merc killed 15/20 strikers (300 mass did 840 mass in damage)
2 mercs killed 5/20 pillars and damage 8 more (600 mass did over 990 mass in damage)
5 mercs killed 11/15 Loyalists and damaged the other 3 (1500 mass did over 5280 mass in damage)
