Well I was serious about the bear's bum, because I think that would be hilarious lol... but no, wasn't saying that should be the ONLY way to level anything. Variety is good. I don't mean variety in terms of other animals, that was just being facetious.
The only thing I'm not 100% on is moving faster while hiding. It's not so much that I'm thinking inside a box, or whatever can be said to dismiss what I'm saying... I just happen to think it would detract from hiding being a special skill one uses in specific circumstances. Differences of opinion are okay. No intention of changing your mind as I don't think that's possible, I'm just voicing what I think about it.
It's entirely realistic to be suspicious of someone wanting to make hiding more useful when the person suggesting it admittedly likes to kill people
Would be silly not to give some thought to potential hidden agendas (pun not really intended).
In a way, that does require me to think outside my own box, as it requires me to think inside yours.
