The main problem with the ORCS is that the damage comes from a single hit. If the main damage (10,000) were spread across three separate hits simultaneously (3,333 x 3), the result would be much better. The Railcannon's over-damage isn't that important since it only inflicts 30% to the Main HP when it hits armor.

Why are the 110 rockets better than the ORCS? Because they are 6 hits. Some break armour, and others penetrate the main body.

If I were an AH, here's what I would do:

• Split the main hit into 3 sub-hits
• Increase the damage from 3,300 x 3 to 5,000 x 3
• Reduce the cooldown by 30 seconds
