There's been times recently in big fights like in bio's where i've been switching zoe off just for survivability. ZOE was great and probably needed a nerf but a double nerf is hard to take. 2250 certs wasted in zoe ah well..it was fun while it lasted
Probably not even that useful now.
Why not have 8 seconds for lvl 1 ZOE
10 for lvl 2
12 for lvl 3
14 for lvl 4
16 for lvl 5
Or even just smaller time increases. What i'm trying to point out is that it should be buffed the more you cert into it.
