Acid pool XSS structure

Using the old acid pool sprite, builders can build this structure that gives xenos who interact with it a temporary acid dot effect when slashing like acid runner. However it is used up after X amount of time OR X amount of uses. Requires hive weeds. Very limited like acid tower

What’s stopping people from just making it near the frontline, and then constantly refreshing it so they have 24/7 acid claws? This is a pretty big buff to damage if you could refresh constantly.

EDIT- Ah, nevermind. I misread it, the structure itself disappears after some time or use. I guess it’s kind of similar to resin fruit, then.
