I've played the game. Felt the awesome power. Blasted enemies to rubble. And ejected quite a few times

But... The Mech needs to find its way into Blockland. Not just the old Mech, Mech Heavy, and Mech Light. I want REAL mechs.
So, here are some suggestions.
This Badass piece of metal is the Madcat.
At 75 tons it will completely and totally ruin your day.
Armaments: 2 ER Large Lasers, 4 ER Medium Pulse Lasers, 2 Clan Machine guns, 2 Clan LRM 20s.

This is the guy who held up the world. The Atlas Himself.
A whooping 100 tons, it is almost never outclassed.
Armaments: 2 PPCs, 2 LRM 10s, 1 Gauss Rifle, 1 Large Laser, 1 Small Laser

Thanatos. Kicks. Butt. It is a favorite of mine.
A brawling Inner Sphere mech, it was designed for Inner City combat. Carries one of the most devastating weapons a city mech can carry. The LBX20 Auto Cannon. Mech Shotgun.
Armaments: 1 LBX AC20, 4 Medium Pulse Lasers, 1 MRM15

YEA BUDDY! DAISHI IN TEH HOUSE.
100 tons, it is one of the few mechs that can outgun the Atlas.
Armaments: 4 ER Large Lasers, 1 LRM20, 2 UAC6s, 2 UAC8s

Vulture. A primary fire support mech, it can still pack a punch up close, besides its mostly LRM armament.
Armaments: 2 Clan LRM20s, 4 ER Medium Pulse Lasers, 2 ER Small Pulse Lasers

Thats all for now. I will update as i see fit. Suggestions for the list are fine.
*Update*
Shadow Cat. Ninja fast medium clan mech.
Armaments: 1 ER Large Laser, 2 Clan Machine Guns, 4 ER Medium Pulse Lasers
