It's not a good time to mine ZEC as they have not confirmed if they will be forking to fight the Equihash ASICs. Seems like a lot of GPU miners have dumped them to provide support for other coins.
Your "it's not a good time" statement is extremely subjective.
If people stop mining ZEC then it will mean it will once again be profitable, if it is profitable then people will resume mining it. Sadly, thats how the world works and as long as something is profitable you can expect someone will try to make a quick buck out of it, regardless of actual support towards the coin.
