Not if it means their preferred faction is gimped to be roughy half as effective as another. This would not encourage me to play the game.
Thass racis', yo. Edit: In regards to the thoughts on the thread generally... If we're equating armour saves to Toughness then Eldar wearing Heavy Aspect Armour (Striking Scorpions, Fire Dragons, Dark Reapers) should be at 110, just like a Space Marine. They should have lower Armour and Health, since those are the Toughness/Wounds analogue in EC.
I don't think you can balance a FPS lobby shooter around by adhering to strictly to the TT game. The people who say Eldar should be more fragile using TT justification should therefore be alright with Eldar moving around 50% faster than LSM/Orks. The fragile fast moving team would be terrible in those siege defense missions unless they had clearly superior firepower.
