This is nothing new at all. The railgun was king last build because of it and is still probably the highest damage output.

The problem comes when you throw in the fact it's been nerfed beyond belief. The turn rate, splash damage, travel speed and range have all been reduced massively. Last build it would annhiliate a missile turret or blaster and this build it just won't happen. If a large blaster gets near you, your dead and the large missile will get you at medium to long range. The only time a rail is better is if it snipes you from afar now.

Saying all this, I had a couple of very close calls last night versus railgun tanks, but the problem comes with the amount of points that the large hybrids require to access and the lack of the marauder bonus. This alone means that once skills are up it simply can't compete for damage against a fully specced armour or shield tank.

If you do keep on with railguns I'd like to hear what you experience later down the line as I hate using the large missiles and loved my railgun last build. I just wish they hadn't nerfed it into oblivion, as it stands it's nothing compared to a forge gun yet it's a bigger, badder version. It just makes no sense how the infantry variant is just that much more effective. If it moves slowers then surely it should be more devastating when it hits?, as it stands it simply isn't.
