With exploding damage, extra Toughness doesn't make that much of a difference anyhow, another area where SW mechanics differ from the game's Damage Threshold and fixed weapon damage ranges. Increase the Armor value? This would help out NPCs wearing Power Armor match off against the players, but in turn make players even more powerful once they finally get their hands on Power Armor.
Extras wouldn't stand a chance against Wild Cards in Power Armor. But this would lead to even more attacks just missing, which is already a common occurrence in SW and quickly gets boring. One idea I had was giving Power Armor a bonus to Parry and penalty to being hit, reflecting the AC value in the games. How to make Power Armor better at protecting a character, without just piling on more Armor value? Another issue is the core mechanic of Extras and Wild Cards in SW, making any NPC underpowered no matter what they're wearing, if they're not a WC.
Part of this is due to the problem of converting the game's three distinct parameters for getting hit and taking damage to Savage Worlds' Toughness value and Parry score, and the generic TN4 to be hit with ranged.
I've long been unhappy with the relative 'underpoweredness' of Power Armor in Savage Fallout.
