I feel like claustrophobia is better than people think. edit: Not Coulrophobia, the healing perk.
Is it good? not really.
does it have it's moments? yes.
Is it still really situational? yes, absolutely.
but is it fun? you bet.
Seriously, try running it.
I'm partial to using it with oppression, DMS (those two go super well together, btw), and merciless storm.
edit: Claustrophobia AKA Cruel Limits.
also, I'd like if it was a TR perk (having vaults in your TR get blocked for the duration instead of within that radius of the gen.) it'd be cool.
