Mandrake is possibly over powered in its current state but before it was ridiculously weak, in fact in the past I never used mandrake to get a bind off because it simply didn't work without hyperactivity.
Other then that some traps occasionally do not work trapping is what it is spose to be, the most comm expensive, rarely used but deadly skill. It also relies alot on luck and your target not knowing defences.
Both bind and binding traps are not much different then dazzle, paralysis, zahir runes, bards song of holding and freeze. Each has a defence and a way out, each leaves you with the inability to do anything other then break out or cure it until acted on.
Thief imagination in fighting. Perhaps it needs a bit more at the moment however with immunities, vast amount of herbs, faster clients and better triggers it is almost a waste to be more creative when it is all so easily cured so no wonder right now thieves are going with something that works.
Just my thoughts on the matter. I overall think the thieves have finally been beefed up a bit for one on one fighting and the results are starting to show.
