Hiya folks 
ive been playing cata for the last few weeks and this trhead and the wiki have been invaluable to me, just like to say thanks for all the help.
Now on to the questions:
1 There are several mutation trees i have never found any specific serium for: medical, alpha, elf-a and chimera, do these serums exist? If not how on earth do you get to the treshold with them?
2 Threshold mutation dreams, if you get one type is that the only type you will get on that char or can you get others if you continue to mutate away from the triggers of the first one? ive been chugging loads of mutagenic seriums and the first set of dreams dont seem to be going away.
3 Weapon CBMs, most of them have a niche, with the exception of the monoblade which seems to be a direct upgrade from the bionic claws is there something im missing with these two weapons?
4 Artifacts, is it just me or is their balance between good and bad really out of whack? i found a fissure event in which i farmed hundreds of them, in nearly every case the downsides make them not worth using over a nailboard/normal clothes, let alone any of the other endgame stuff.
5 Labs, reading through this thread people talk of labs as being really scary places, in my experiance they are the complete opposite, with the exception of the turrets and the occasional basic zombies the only threats are locked in cells or out of the way rooms.
6 Weapon damage, if a weapon is listed as having 20 bash damage and 40 cut damage are those two values added together against mobs that dont have any specific resistances to either?
