hopefully, the batman-adv version you are using is newer than 15.05 ...

Why not ? What should prevent nodes or clients to choose another batman-adv
gateway ?

Can you elaborate ? Are you comparing bridging vs routing ? What's the main
difference between 1.1 and 2. which makes you think it works better ?

You can always ping or transfer any IPv4/IPv6 payload over batman-adv
regardless of your WAN setup. In fact, you could operate batman-adv without
any WAN uplink at all.
