Flawed

Rate my second mech!

I really wish I could have actually experienced portals...
But it's a shame they seem to have quit doing them.

This is a "Imma head out" moment.

Kids, this is why you shouldn't play with BackBreakers and SeraphBlades.

Battalion Incinerator lives on, even when dead.

The only item that would have any purpose on the mech (unless you want Explosive items on my Physical mech) is a Selfish Protector.

I would say it's pretty good. The things I recommend you change are...
1) Your Regeneration looks a little low. It's fine for now, but I would recommend trying to get it up.
2) I know you don't have a E-M Savior Resistance, but I think you need a little more Resistance.
3) When you get one, replace your Massive Lava Feet with Massive Shocker Feet.
4) And of course max out your modules.

True... if it's the chocolate sold by Hersheys.
Next person is a high-school dropout. 

Well, it can be a great deal but still unaffordable. If someone was selling a tank that costed 1,000,000 (1 million) USD, and they sold it at 50% off, it'd still be 500,000 USD.

Well, I only have 1 mythical and he let me in, so...

Who knew, out of all the things to start a war in the comments about, it would be about whether Chimaera or Windigo is cooler.
Anyways, what's wrong with trucks? It's cheaper to salvage a truck and use it instead of making an entirely new one. So yeah, Windigo is better with in-game stats, real-life pricing, and looks.

Windigo is the best torso in terms of look. It's super cool.

Yes, but Nightmare and Windigo look much better.

False.
The next person is short and lives in the medieval times, lives in a hole in a hill, and has been met an old man who apparently knows otherworldly powers and is accompanied by some other short people with odd names who asked the next person if he would like to steal from a dragon that lives in a mountain.

The only reason I can think of is you don't have a torso and/or legs.

For your first question (if I understand it): no, I would recommend you focus on making it heat, energy, or physical, and not switch types because you don't want to divine your Corrupt Light and then switch to Energy.
The second sentence: yes, I know you just joined, but you already spent some stuff upgrading Interceptor and I just want to let you know that Nightmare is the better torso.

Here are some tips for your current mech (even if it is currently bad):
1) Are you trying to make your mech have a single "type" (heat, energy, physical)? Single-type mechs are generally better than hybrid mechs (of course, an all mythical mech hybrid will always win against an all epic single-type mech).
2) Use Nightmare for your torso. It starts at common and goes all the way to mythical, it's better than Interceptor. Also, I don't think Hollow Cyber Armor is obtainable anymore.
3) You need a lot more cooling. If you get overheated and you have terrible cooling, then the game is over.

I would say to replace your Nightfall with a Magma Recoiler, or any recoiler, as soon as possible. Remove your Falcon and replace it with something else. Add another Dawnblaze or add a Corrupt Light, because I don't know how effective your mech will be after you've used up all your uses with your Desolation. These are all in my opinion, of course.
That's all!
