Since there's some interest, I'm updating and reposting the Highlander 'Mech of the Week article. It's going to be a bit longer since a total of five variants have been published since the article was written in late 2009, including two new IIC variants.
EDIT: Done! In general, they're very dangerous 'Mechs. I pointed out a few very minor flaws in the article but trying to exploit them isn't easy. It's worth trying but a lot of it comes down to luck. The 2 and 3 are horses of somewhat different colors. The 2's higher heat and prevalence of explosive crits can be problematic but it's not useless by any means. I'm not fond of laser heat sinks for a couple of reasons (not least of which is the glowing technicolor anime air they lend to events), but if it points everything at the enemy for a couple of turns, he may not be left to argue the point. Their bonus against external heat loads can be useful, too. Infantry may mutiny before walking in front of one, too. The 3 uses a HAG/20 and gains ECM. I'd rather have the Gauss rifle, all told, but HAGs can certainly be useful, and at short range, the additional clusters will make some targets even less happy.
