i will come with a basic stat-recommendation
get around thes values, no need to be accurate
250 seems to be some softcap, higher than this, the incrase in effect is smaller and thus its better if you invest into another stat (this does NOT apply to brutality / determination / proficiency and bloodlust/ lifepoints)
special stats:
critchance = 250 not for bard as there are rubies for 100% critchance
critdmg = 250
doubleattack = 250
normal stats:
PVP = 100 prof, rest brut, not deter (unless you really know what you do)
high caution and rest to lifepoints
cape, gloves and shirt cant be set tho these so you can go bloodlust or in case you are a healer survivability
PVE = full determination
on youtube there is a good video from dragagon which explains about stats:
