Looking at the revealed 'Mechs so far, i feel some deviate too much from the originals.
The Nova gained waist and has hulked out unnecessarily. The Mist Lynx looks more like the Sling than the original Mist Lynx, not a bad look per se but it ain't Mist Lynx. The Executioner's legs feel way too small/thin, arguably the more agile look suits its stats but... eh.
The Timber Wolf's not bad but i don't really see it as improvement over the previous model, prefer that. It is definitively a bit fat. I will call that one Fat Cat from here on now.
The Adder, Summoner, and Dire Wolf, look OK. The Stormcrow's OK but i don't like the laser re-arrangement on the arms, even if it is more sensible than the original but this is pretty minor.
The Grendel is an improvement certainly. But i never cared for the 'Mech so whatever.
The Shadow Cat looks good, it needed a new model. Though now i wish there was a model patterned after the MWDA mini, that'd go nicely with the Avalanche and Wendigo.
