Volskaya is the newest battleground. So far it hasn't been a good Murky map but am still working on it.
Bribe doesn't seem very impactful so I prefer Egg Hunt on this map.
I originally thought March of the Murlocs would be good on this map but it hasn't worked well for me. The objective zone is wide. So the enemy team can see me star the march and just walk away from it. Even if it does hit them their towers are right there and they can usually escape.
For the first object I will grab our camp and push with it. It forces on person to come up to deal with Murky so my team can try to win the 4v4 fight. The first mech is pretty weak and generally with a decent team we will come out even.
Other than that the standard slime build applies.
