While the Madcat is good, I have always been more partial to the lighter, jump capable mechs. The Uller, for example.
If you want to see devastation, go for 5 ER Large Lasers (w/ Clan double heat sinks) in an alpha strike. One strike on a leg and you have a nearly functional mech for salvage...
I know these could be a lot funnier, but I'm too tired. The Timber Wolf owns the Madcat (don't even know it) but they're both pwned badly by the Summoner.
first off... the MadCat is the Timber Wolf... its just a difference in name designations between the Inner Sphere and Clans... and yes... the MadCat is far superior to both the MadCat MKII and Thor.
...yeah, im a dork
