Today I was farming Act II on normal difficulty with 250% magic find bonus trying to find some decent rares. Of 25-30 rare items that I found all armor items had 4 affixes and weapons had 4 to 5 affixes.
I know that items can have up to 6 affixes (source), but apparently on lower levels the limit is 4 or possibly 5. I would like to know on what exactly maximum number of affixes depends (is it act and difficulty? Or iLvl?) and what is the earlies point in game where I can start getting items with all 6 affixes. Is there any official (or unofficial) info on that?
Also, I suspect that there is a minimum number of affixes for specific iLvl as well (have you ever seen rare item of 62 level with just one affix?). Any information on this will be appreciated as well.
