Well, it seems you're right there astax (doh!). They ARE slow and it took me a match to realize that.
Now i think of a new solution: how about increasing the supply demand and price of the LRF?

This would make spamming the LRF more demanding than it is now, which means less of them to deal with.
If there's a problem with that, then idk how to balance it anymore. I just want to end the LRF's overpowered characteristic.
If anyone can think of anything to balance it, i'd like to hear it.
