If you feel like a lot of reading, the last thread with this very name got a bit heated, but there's good information to be found.
For my part, I can't stand the Couger. I think its terrable. Its too slow and too weekly armored to survive, and it carries too many guns and of too high a quality to avoid being a prime target. It has the power (and the BV) of a quality heavy, but the armor of a light, and not even full armor, and movement no better than thouse heavy mechs that are shooting at it, so it can't even hope to get away. Yes, its a great mech to bully other lights around, and rightly it should be. The Urbie does well in that role too, because it trades away so much engine for guns and armor. But, the Urbie can't hope to catch light mechs if they want to bolt, and the Couger is in a similar boat. May as well use a Nova or a Timby as your bully, and lessen the risk that the other lights, which still pack some punch, hit you back and score a kill.
The only thing that saves the Couger from being absolutly useless is that it has some of the best executed configurations of any omnimech. Twin LPLs on the Prime would make any mech look good, and twin PPCs with some heatsinks is such a welcome change from mechs like the Adder Prime, Nova A, Hellbringer Prime, and Warhawk Prime that we're prepaired to ignore the other deficancies it has vis a vis thouse mechs (low speed, low armor, no TC). I've argued that if the Hellbringer had the Couger's configurations rather than the problematic ones it infact got, it would have been the most beloved mech out of TRO3050, even with its minimal armor and antiquated tech base. As it stands, the Couger A has about as much ranged punch as the Hellbringer Prime, and the C is broadly similar to the Hellbringer B , but with even less armor and no more speed! If the Hellbringer was a quick way to kill a lot of power, what is the Couger?
The only time its a good use is when you're ballancing by tonnage. If tonnage matters, the Couger is one of the kings of the game. But, if its about cost or about BV or about mech for mech quality, the Couger is not. Even for its tonnage, I prefer mechs like the Hellion or even the older Adder, if not for the less efficant configurations.
