No you don't, tinc doesn't have single points of failure if properly set up. 
Just make sure each node knows of more than one other node for the initial 
connection. Once a first connection is made the other hosts are 
auto-discovered.

That said, tinc certainly isn't perfect, and I'd be hesitant to tunnel
low-latency packets over it. Once the persistent connections between all hosts
are in place everything runs fine, but when connections fail (for whatever
reason, mostly network problems) and have to be reopened you have extra
latency and packet loss at that time. We're very happy with using tinc between
various networks, but we don't do any high-performance (be it latency or
bandwidth) data over it.
