I keep waiting for echo prices to drop again to try it with the avalanche. As it should nearly cut the reload time in half as its pretty close to 7-10 seconds.
Deadman is probably the best bet for Thyrsus though as your picking up the 20% reload. plus what ever you get from the fly wheel. Which might be higher then any of the combos with Hadron 10% and averaging limited to 40%.
I do see some people running Kaiju on small fast builds with some success, but I have more luck on heavy slow builds myself.
The ones running it on fast builds do a lot of relocating, and just keep moving. But they don’t really need that reload boost either, since they’re usually moving while reloading.
