Well, every other infiltrator isn't exactly a master of matrix dodging either.
The most durable would be storms I believe?
All others are pretty damn fragile and most certainly ineffective at all ranges.
(inb4 someone rushes in drooling and screaming commandos, check out their scaling first)
Its more a dig at brit mainline having more dodge than a doctrinal elite unit AND the ability to 5 man because reasons.
Partisans are a boat load cheaper so its understandable for them to not be terribly durable,
Storms are fine as is, they seem just durable enough for elite forces but not too strong as to make them. To easy to use.
Pathfinders/ JLI are a different breed of unit so i dont think they can count in this discussion
And commandos while they DO have range restrictions they also get demos and a bonus attacking out of stealth and iirc have a silly high rec acc (isn't it towards something like .6?) And an extra model.
O dont see any reason for falls to not be .8 RA. Its a small buff but i think its a reasonable one given their price and thus reinforcement.
