Tyrant multi-tasking would be very useful for tyrants but it's fairly set that Acro won't been getting it, and it seems like this is one of the main reasons why multi-tasking won't be added.
I feel like there are some ways to make Acro's stomp a decent chunk less risky to make it more survivable for an Acro in a firefight while making it more of a side-grade to tyrant multitasking.
This could be done by boosting Acro's sustain or maneuvbility after stomping so it can survive the attacks or have enough speed to escape the massive target it has put on itself.
1 - Acro gets 100-200 health per stomp kill. This would give Acro a small boost of health after killing 1-2 humans, giving it a bit of sustain though not as much as a bite.
2 - Acro gets 25-50 health per stomp hit. Since Acro's stomp is a pretty good disruption tool, Acro could stomp down on a crowd and get some health that could give it time to escape while being fired on.
3 - Acro gets a brief acceleration boost after stomping (or just in general). Acro's stomp is so risky because it has to lose all of its momentum to stomp and then regain that momentum to run out, usually giving plenty of time for it to be shot at, this would make it so less time is taken getting back to full speed.
4 - Increase the armour Acro gets while in the stomp animation to 40-45% . Right now, Acro gets 30% damage reduction while stomping, as much as eating but without any sustain and losing all its speed, making it a sort of temporary damage negation before it is shot with full-force. This buff would make it so while stomping the acro a tiny bonus amount of damage negation so it can last a little longer.
The armour increase could also experiment with disabling the Acro's crit-zones while stomping.
