Because you have an iron plating that is really heavy, you can remove that and put on the claw. Your claw will have way more HP anyway compared to just an iron plating, and ultimately have more HP than your legs and iron plating combined. I recommend mything your claw before putting it on your mech though. And lots more specials that move you around other than just a single grappling hook. And try replacing your ultrabright and heat bomb with nightfalls, because this will really bring your ranks up. Mechs that use all three elements don’t do so well. It may take a while, but trust me, it is worth it. As with the spare weapons, you can put them on your other mechs.
If you do it well, you can get an awesome mech like this. You might want to replace the interceptor torso with another torso though, because there are many torsos better than that.
Phew, that’s a really long reply for me.
