From a GM perspective first, I've already found numerous ways around the poppers. Either don't spawn CIS and use organic NPCs because of the limits 241st has already placed on itself with these. At worst, they'll throw one and clear out about 15 droids tops and have to wait until they respawn (which we monitor to make sure nobody is just spamming). While steamrolling can be a concern, I haven't seen a single instance of it just due to how we've operated and how GMs can easily respawn them. Or we've just missed the throw entirely lmao
From a 241st perspective, as I said we've already placed pretty strict limits on it such as not using it on organic NPCs, not throwing it when friendlies are even relatively in the line of danger (due to the stunning and not being able to defend themselves), etc. We also suffer heavily from the RPG mindset of "I only have one of these, I'm going to save it for when we need it!" and then we never end up using it.
Also, at worst, the GM can just tell 241st not to use the droid poppers because of tick or pacing and we'll happily oblige.
