Changelings, and why they're just too damn powerful

[BaneOfGiygas]

Perhaps one of the biggest ways to help mitigate the changeling's unstoppableness is to, plain and simple, give them some sort of punishment for being unstealthy. As things stand, changelings never have to worry about getting caught while feeding because they can just neuro+acid the intruder and get TWO meals instead. Perhaps force a cooldown on all changeling abilities during feeding and a while after so that a ling is required to feed in actual secrecy instead of wherever happens to be convenient, lest they be forced to fight without any of their abilities.
