Faraday nerfed too much?

Faraday got not only nerfed in costs, but also in stun time.
2 seconds was less than 8 of the venom, 1 seconds disallow permanent stun.
( it has a longer reload than stun time )

It is a building which have less than 0.8 times usefulness than the unit-equivalent.

Originally it should allow pyros to do a little damage to them.

stardust + faraday and pretty much everything that comes close is good as dead.

Which means you need like 2x metal
