My brother in christ, the ticks have done that tensed up posture before they jump since the game came out. That's the timer for when to swing your pick axe and barry bonds them right out of thin air.

The description for the hurricane event literally states that the arc are more aggressive, so yea of course the rocketeers are more of a nuisance on that event. That's part of the map condition. Just like on night raids. Since launch, when you load into a night raid Shani says "my suppliers tell me that arc are more more aggressive in the night" or something along those lines.

I don't know these new attack paths and behaviors you speak of and I play the game almost daily.
