I think the flaw is in that people demand the absolute maximum TH from a THF- because the idea that -1 TH will cause them to lose millions of 100 pieces/uber items and suffer horribly as a result.
It's why I'd honestly love them to just make a really nice +TH/+Steal/+Despoil H2H weapon and leave it at that. Then if you want the super good shinies drop rate, you're not even going to whine once about the lower DPS while I try and punch that mob with a 300-cap E-rated H2H skill and yoink it's purse for good measure. Putting TH on a dagger just leaves us wondering.
