Diablo III: Reaper of Souls

hahahhahahahhaahahahahahahh

with krider shot you can just shoot at walls and well everything else will seem like a buff no?

Without Kridershot, everything seems like a nerf.

I'm trying to figure out what the hell Spitfire is doing. It looks like it'll shoot extra rockets depending on the number of enemies "in range", which isn't the range where the Sentry itself can shoot though there's a cap?
Basically, there's some range where if there's a monster inside it, Sentries will shoot at it if you shoot, even if they can't reach it. Monsters inside this range makes Spitfire shoot more rockets? I was definitely seeing an instance in a GR where my Spitfires were shooting 3 rockets each time I fired, and they could all home on the same monster. It was a really tricky position to get into because the Sentry and Elemental Arrow itself was barely out of range to hit, but the rockets were able to connect.
There's also the case of Sentries still firing regular bolts after they shoot a spender. It doesn't slow down your spender at all, but it might be the cause for extra rockets. It's more noticeable with Polar Station and a non-Frost Arrow skill that it occasionally happens, but not all the time. Since this happens, Tasker and Theo might still increase that particular interaction.
Here's an example of what I'm seeing:
5 Sentries performing auto-attack. The rockets more or less come out in sets of 5 together since the sentries are fairly synced and you can see the cluster they form.

 Spoiler

Here, I fired an Elemental Arrow. More rockets appear.

The top of the new Marauder is significantly more powerful because of constant Elemental Arrow with Kridershot with another spender, and the 5 Sentry bonus with Bombardier's Rucksack. Without those, you're pretty out of luck if you're not running Immolation + Mortal Enemy because of the inconsistency in damage output and lack of bonus from 5 Sentries.
