Okay, I'd like to throw in my two cents here...
As pointed out earlier, I knew that the Elf Bullock would be a little too strong at this moment, and so I intentionally nerfed it to make it more balanced compared to the other mobile suits. 
The Hrairoo, or Fiver, or whatever you wanna call it, is comparable to the Gundam as the regular Gaplant is to a GM. The TR 5 was made to be able to mount large amounts of equipment, comparable to the Dendrobium, but that's not til later issues of it when they add things like the Psycho Gundam Manipulators. It is a transformable mobile suit that can become a mobile armor by being customizable. Truthfully, if you just use it normally you could probably make it a glorified Gaplant with a Blade Rifle, which is a super heated rifle that can block beam sabers, similar to the G-Arcanes. Just like it, the rifle can be destroyed if not turned on in time.
Edit: Fiver is actually the TR5 upgraded into a legitimate Mobile Armor.
