Let me comment on this, by explaining "Rules as Intended" and "rules as Written"
Every "Rule" ever created for everything from DND to CM, has 2 sides: the Intent, and the Written. The Written of the law, is the actual words describing what it's specifically preventing or what it's limiting. The Intent, is the reason the rule was created and what general behavior the rule is trying to enforce or avoid.
This rule for example, is written as:
Do not Kill infected hosts (once they have the icon) if they are defenseless or nested. It's counter-productive to your cause of spreading. If a marine escapes the nest and uses a weapon to resist, THEN you may kill them, but you should try to tackle and nest them. Remember: The most hosts you get, the more aliens you get.
Basically, it's trying to stop hosts from getting murdered in nests for no good reason, while still allowing aliens to use huggers as a weapon to stun-kill.
The INTENT of this rule, is to prevent aliens from killing marines unnecessarily (thus dwindling their own numbers), and give the marines the chance to possibly escape. The rule was written to try and still let carriers and the few people who use huggers as stuns, to be able to do it, but it's meant for use in large combat, not one-on-one.
So, my question to you guys is,
how could we re-word this rule, to prevent maiming/harming hosts who are hugged and outside the nest (but not in a large group in combat) to increase the change that the marines will make it to the nest and not get maimed?
