Well as I explore (yes even after almost a year I still find new things)  I tend to try and sample various thing , not only to see if I can but just for kicks lol..
Some things have been brought to my attention , 
1:) You don't  sample human looking bodies (mimic) some you can and if you do they WILL change its look.   Try and remember what it was you mimicked so they can prevent any further issues.
2:) We don't sample Bosses , which include but are not limited too.. Champs , Peerless , Rare "Named" , Event mobs , and Quest Mobs.   Most I have witnessed cannot be sampled from Stats (Envior , Prow , Mental) but we can still Mimic ( which is frowned at and shouldn't be done.)  Mainly because it can out right kill the monster and no one gets any loot (no body) or any other reason they (staff) may have.
If you do sample an above listed, other then mimic, you should let them know so it can be fixed. This will keep it somewhat balanced and your not running around with a bio you worked so hard for just to have it taken (if not reported)
Remember a mistake is fixable , but a mistake becomes an exploit when you know and don't saying anything.  GM's can see ALL chat , PM's , and Guild Texts.  They will know when and if you have been warned or informed about the mistake.
Bios also have max caps (which I think should be raise at least 20% to make them as good if not slightly better then a 45 breed pet with pack instincts 2 slots =/ ) and can be found on the wiki.  I would report any overages ASAP , again it can be taken and deleted if not reported. 
I like bio pet crafting but don't use them for much but looks for again the breed 45+ pets are better.  Not skills wise mind you just pure damage cause of less slots = more pets
The main goal is to have a cool pet now , as to in the past they were for hunting with. (some still do) And have fun  don't forget that part  !!
I know this is all posted some place just wanted to throw it out their again 
Adjusted to Meer Eternal cause it was human looking ( wont say what I used to get it )

Awesome post.

yeah was running out of points and wanted the stats  prolly just give him away like I do the rest of my bio's anyway heh   low tame needed so good for new player   =)
