The web hosts that I work with, one of my requirements is Live Chat. I do not like any "bots" or "fake help". While it can be useful for some, it's not helpful to someone that knows what they're doing.
I generally open a chat and if there's a level 2 tech or an admin that can assist, great, otherwise I redirect to a ticket.
I have had instances, infact I ran into one just this weekend with a plugin that I was installing. I contacted the plugin provider (who had live chat), and when I started the chat it said that I can enter my info but staff wouldn't be back to answer until Monday. I was a little annoyed that it said "live chat online" but I filled out the ticket anyway, and surprisingly enough, I got an answer late Friday night and my question resolved.
I would much rather have had just a ticket option than a fake "we're online" message.
