So stats could be 'Conclave Standard' or 'Rulebook Standard'
Well, as far as "Rulebook Standard" one issue I've noted is that some players roll their dice, get a below average roll, then think "well, this character's supposed to be really skilled", and re-roll it because it's not "right".
This of course disregards the fact that the basic random profile already represents the best of the best. Not accepting a below average roll therefore multiplies it further to "the best of the best of the best".
Okay, if you're really going to play that way, but not accepting less than unbelievably exceptional is... well...
...but wasn't too badly received despite the fact that there was no miniature to back it up (which is something that I would consider to be important but that's subjective).
Well, that very much depends on the way people work. 90% of the time, I design the character, drum out the concept and details until I'm happy with them, then make the model to fit those criteria.
Sure, I could wait until I'm done with the model before posting a profile, but then if someone makes a suggestion I like, I may have remodelling/repainting to do - and indeed, if I've got a model, then people might be less inclined to make suggestions for changes.
This approach (which we'll call "Character driven model", or CDM) is the reason I sculpt my characters, because that way, my creativity on the character front won't be stifled by what parts are available.
Yeah, many prefer to have the model before the character ("Model driven character" or MDC) - even I on occasion will make models on a whim.
And every now and again, there's a character where neither really comes first.
In the end, none of these ways is the "right" way.
Before anyone jumps on that "none of them is wrong" statement and tries to twist into the "power level" discussion, I would point out that the two discussions are not the same.
They are both player preferences, but while power levels can't really be mixed, there's no problem with mixing characters which were made one way around or the other.
