I've been playing more since then and even changed my mind on a few things:
- Analysis paralysis only happens when all the monster types happen to have similar stats (and the room is full of them). Otherwise it is an easy decision to start attacking the weaker monsters first.
- I personally would like as many tactical options as possible concerning each monster type (like the wolf trap positioning). In the end exploiting the enemy quirks is the whole point of the exercise (and very satisfying).
