I'm playing on 3 different servers and there usually is quite a lot of folks in the team that don't really know what to do. So i had a little idea that could benefit everyone and make ninja wars even more interesting. If there would be some kind of battleground in the group section where people could team up and check out the synergy of the 3 people on their side.
So basically it would be 3vs3 from your own group. But it would provide a really interesting testing place to get ready for the real war. Since we got these new ninjas there could be some really interesting combinations with right people.
If you just want to practice and test synergy you c*ready do that with regular duels. As long as both sides have the indicator that they belong to a team(regardless if it's a 1,2 or 3 man team) the duel happens normally with everyone in it.
