Playing crowd control in Warframe often times feels super weak, but there are still some situations where you want a dedicated CC build.

For example: Some people still prefer to farm Endo the ‘old’ way (in the Rathuum Arena) and use a [Nidus] or two with some [Nekros].

In those situations, having a crowd control build is essential and needed.

But you can also play this version in every endless mission and simply grab mob groups from far away while building your mutation stacks.

Yes, your damage output won’t be great, but you’ll be able to reduce incoming damage simply by controlling the battlefield and preventing enemies from shooting or hitting you and your team mates.

You also might want to add extra duration, so picking [Constitution] over [Streamline] (or [Augur Reach] if you don’t need that much range) can be very beneficial.

You might also want to think about Narrow Minded, but the range reduction is only viable if you know that you won’t need the range at all.
