Ok, so the STC-2C Striker is the ugly step-child of assault BattleMechs. Not beloved enough to warrant the attention of a BNC or ZEU upgrade, there are only 3 variants published in the MUL and no assembly line intact (after its destruction in 2867). The STC-2C reminds me of an Enforcer's loadout, just increase 30 tons by adding a PPC, modest armor, 4 heat sinks, and a pair of medium lasers. Oh, and drop the size of the autocannon.
It feels like it wants to push smaller 'Mechs around, and might have some trouble doing that with heavies. Sure it keeps pace with heavy-assault lances, but it must bracket its weapon fire to not overheat significantly. Outside of the Third Succession War, I suspect a Striker is too slow to choose its range or adversary. Perhaps this is a blessing, because using those Medium Lasers can kill it with heat (and mobility). Most turns, I suspect the PPC and the AC/5 will be its main fusillade. The armor is not heavy enough to make it a proper assault juggernaut, so it's a heavy brawler or some hybrid, like the Victor.
Well, what if you made that armor stand up, say by making it hardened armor? Now that the Striker's armor can withstand a little more punishment, it is now a true juggernaut, choose a destination and fight anything that stands in your way. There is a lot of free space on that chassis, so why not make some room for some heavier things, say with XL engine (we have that Hardened Armor now) and Endo Steel II. Double Heat Sinks make alpha strikes manageable, so much so that we can squeeze a little more range out of those Medium Lasers, upgrading to ER Medium Lasers. And while an AC/5 is not truly intimidating, a RAC/5 is. Now you have an actual juggernaut with places to go, and 'Mechs to pepper with 5-point damage shots to spread around.
