[gameplay] taking dmg in bard's tunnel

Ennemy bard created a very long tunnel and almost all my team took it (he was low). On the other side, GP barrels... My whole team was on the other side but I was about half way through the tunnel and took the damage from the barrel. I was very far from the aoe damage. Didn't die, but not the first time I notice taking AOE damage while in Bard's tunnel.
