BattleTech is known to have it's winner and loser of designs, where their not suppose to be spectacular and allow others get more attention.
Storm Raider i think was simply not designed for our game. I suspect A game designer for MWDA came up with cool looking figure, came with descent (i don't know, I've not used a dial for this thing in years.) dial for it while putting on random stats on the figure. I've heard they did use HMPro for some of them, but not all of them. I think Storm Raider is victim of that.
Given how the design was born into age of Battlemechs are rare beasts outside the military that limited it's numbers of Mechs to 2 mechs out every 4 vehicles if the Novels were to be believed. The Raider should have been out production when 3145 range in New Years. I think perhaps it could be interesting design in Solaris, but it barely i think a Raider or a harasser.
I remember reading a member of Stormhammers (republic splinter group) used one these Mechs during the attacks against then invading Jade Falcons into Perfecture XI (9) on their way to Skye. I thought was funny MechWarrior raised his Hammer yelling over comes "Cowabunga!".
Thanks the article, Wantec!
