If the Rangers are in, so will be the snipers of all other factions, think about that. And the Eldar have so many wonderful Aspect Warriors! Do you really want Rangers instead of Aspect Warriors' greatness? But even if Rangers are in, their stealth mechanics is pretty simple, they are invisible at a long distance, and can be noticed on middle ranges by kind of Predator-style shimmer when they move. If they don't move, they are much harder to notice. But the Striking Scorpions have to adopt some other kind of stealth (though they pay a great homage to Predator with their looks). I like this: But it could happen, that we won't normally see enemy name-plates anyways (unless pressed a button or not even that - unless you are killed). Still, if the game uses 'spotting' mechanics (like Battlefield, MWO or many other games), it makes really difficult to spot the enemy if it doesn't bear a 'spotted'/'not spotted' marker above. This could work well with the 'better cover usage' mechanics promised to Eldar. Or we could use something like this for Scorpions, but without cloaks: Still, normally Scorpions do not have infiltration, it's an Exarch power to hide his squad.
