I have trouble with the whole realism thing due to:
o Most of us talk. (Yes, yes I know of the hyper-realistic roleplays - so awesome.)
o We all have NAMES. (Apart from ones called 'Wolf' that I see occasionally)
o It is hard to find the right markings to make oneself realistic and not boring.
o The pack we are is NAMED.
o We usually have RANKS like 'hunter' and 'fighter'. The wolves in irl packs do these things yes, but are not SPECIFICALLY ordered to do so.
If we went by actual realism, every. single. pack. should be semi-realistic. (Hyper-realistic <3 I didn't mean you.)
The boundaries between each category are hard to distinguish, I'm afraid.
