It would be kind of cool to +1 the word for protection. And then it has to be not that more +1 times. You wouldn’t have to “secure” it too much from cheaters, once per word per session would sound fair.
Whatever has to be killed will be killed, though it wouldn’t be terrible to “stick up for a word” would it?
I did rampage the list a few times, I targeted ridiculous words, a few I hated, and sometimes thought of pairing down variations of words I left alone.
