Behold C.R.D, my best bot as of now.
Built way back in October 2016 (or something like that), this mech still has not in any way dropped in power.
Primarily a medic, C.R.D is very protective of his teammates. His nanos may not heal much, but in a tight group they can prove to be invaluable. C.R.D is built to suddenly release huge damage in the form of a plasma volley- and then heal with its Binders, which consume no energy. This allows for a hit-and-run playstyle.
He isn't just for looks- C.R.D is also a very versatile robot. I'd recommend him for TDM, but be wary of bombers.
