Snipped from RFC 3315, section 1.1 is: [Clients and servers exchange DHCP messages using UDP [15]. The client uses a link-local address or addresses determined through other mechanisms for transmitting and receiving DHCP messages.] Using link-local for DHCPv6 has the advantage that well-known mcast addresses can be used for clients to communicate with the server or relay agents. RFC 3315 also mentions such an advantage in section 3. Of course, even IPv6 mcast uses link-local address. So really, it is not wise for a host to not use a link-local address at all.
