Ok, I see the link you are making. Personally I see Grand Scourge remaining a separate character to Scourge until they make a back story linking them (e.g. how did he become ‘Grand’? Or is he a puppetmaster of many Scourgii?). The TFWiki link above mentions that Grand Scourge is a separate entity in his new eHobby bio but the article did not provide proof of this either. Oh well.

By the same token i think CW Onslaught would make a better torso for Ruination but still I am all for more combiner limbs so bring them all I say.
