Please just remove this godforsaken mutator entirely.
Why am I even getting rid of weeds as a marine? What's the point in clearing an area when it doesn't matter and a xeno can just heal up regardless? All this did was remove a layer of strategy and counter-play. Beforehand, xenos had to get drones to weed in support of an attack. Marines had reason to remove those weeds. Marines knew if they were moving into weeded territory, that this is where they could expect aliens to lurk.
Now it doesn't matter. This mutator didn't add anything to gameplay; in fact it objectively reduced the strategies used and available in exchange for letting xenos play lazily and with less risk.
On the xeno side, it's just rolling eyes worthy. I can run around as a lurker wherever I want, moving as fast as a runner, going invisible to pounce/kill isolated marines, healing while I'm stalking around behind lines, and if I get in trouble I can take off and be 20 tiles away in a couple seconds, heal up within a minute, and be maiming/critting/killing another marine within another minute. All by myself, without any need for any support castes, teamwork, or any real sense of danger or tension. NEVERMIND the fact I can REST as an elder lurker and OUT-REGEN the damage being on fire does, while OFF WEEDS. And while I'm running around, I'm constantly healing smaller amounts, which enhances survivability tremendously for the faster castes that only get popped by a bullet once every 20 seconds.
Yes, we need more mutators that aren't just pure stat buffs. But holy christ this is actually cancer. Why can't the devs just add common-sense mutators? Take ideas from the playerbase after some round-table discussions on gameplay and balance effects on the forum. I guarantee you'll get better ideas and better balance.
Just stop adding these gay xenobuff mutators. You aren't making xenos more fun to play, you are making xenos easier to play for shitters.
I hate this mutator as a xeno player, and I hate it as a marine player.
