I cant agree.
A char approaching a pack of Ulbernauts for instance should sneak and observe, spotting out the weakest one of them. Every race has younger and older individuals, leaders and followers, who all vary in strength.
I remember long time ago I rped a hunt with my char and some friend, and he was seeking out the most powerful one for certain reasons whatever. That moment already I wished there in fact would be more of a different, yet all were of same strength of course (Volcano Ulbers).
Not that it spoiled our fun, but for rp it makes much more sense, in my opinion.
People can adivce newly ones like you propose, Coneitic, yet they could also tell them of races and instead of pointing at the one always being the weakest, they could rp it and advice to watch out for pack leaders as they are ferocious, especially with whelps around.
"the rouge that spawns outside of hydlaa gates. he is easy"
To me that doesnt really appear to be rp at all. In that case I would say, I dont care much if people do their ooc-play.
To strength modulating: Should be within some limits depending on sort of npc of course. maybe like the strongest possible Tefusang could defeat a weaker Ulber. Or something alike. I wouldnt think to introduce a random-count factor for strength (and/or other skills and stats) of npcs shouldnt be that hard? I admit I have no clue how it is coded though.
