Since the release of the Battleground, there were two resounding pieces of feedback: the map was too large and teams found it difficult to engage with each other due to the amount of ground needed to cover while picking up Warheads, and very often the game either ended up being a base-race as each team takes a Junk Swarm Host and tries to push opposite lanes to end fastest. On release, Warhead Junction had two Junk Swarm Host bosses, no Sewage Tunnels and only one Watchtower.You'll almost never want to use a nuke on a fort if all towers and gates are already dead, it's better to just attack it and save the nuke for difficult-to-break sieges.Nuke damage versus Heroes cannot be reduced via Resistance or Spell Shield, but it can be shielded with Heroes like Abathur.You can also nuke a boss to capture it faster (but this is very niche). If you are defending alone against a big push, you can nuke the entire enemy wave, merc camps, and incoming boss.
