Ebon Jaguar has only 384 armor (192 in Battletech) and the Timber Wolf has 460 (230 in battletech).
These values on Omnimechs are supposed to be non-changeable, period. Thus the Timber Wolf has superior armor. However PGI stated "We realize that this would not be good for the nature of our game."
Another thing to note is that Ebon Jaguar (Cauldron Born) is NOT supposed to have torso twist of ANY sort. The legs are mounted to the torso and there is no pelvis.
The proper advantage the Ebon Jaguar does have is its squat design, making the cockpit height at 8 meters when 'standing' and its shoulder weapons at just barely less than 10, making it fantastic for cover-based shooting, ambushes, and making it difficult to shoot from the front or side (which makes up for its 'width'). Being such a compact mech allows it to be more difficult to hit. It is also a weapons platform in exchange for its armor. In comparison, the Timber Wolf is supposed to be 12.6 meters tall (smaller than MWO's Hunchback).
Sadly PGI and its scales decided to 'harmonize' mech scales. The size difference would make great sense if the armor was locked as an allotment of space.
The actual canonical omnipod weight available is 27.x tons for the Timberwolf.
The canonical Omnipod weight available is 30 tons for the Ebon Jaguar.
The Timber Wolf's engine rating is 50 units above the Ebon Jaguar, necessary for the much heavier Timber Wolf to obtain the same speeds. Much like you can't put a car engine in a semi and expect it to do any good.
The speed a TBR would have with the Ebon Jaguar's 325 engine is: CLAN XL ENGINE 325 Speed 70.2 kph.
Fun, no?
