why did you go great Str rather then great Smite X for the +10 str at level 41? this would give you the great smite ability for Mass smite damage and still have comparable str, this one however would be alot better for leveling and then reincarnate at level 60
That being said there're better modern lash builds with 1-2 fighter splash (with the introduction of leg/paragon weap spec). Especially since losing one epic bg feat like Epic Toughness is not a loss. Those starting stats and the ''first point in cha'' make no sense (easy +1 to dex checks just moving 1 starting str to dex+cha, and then all points in str, also start with less con is advisable). Nowadays, CC blackguard should go str arti over con one (or int? really?) due to changes to poison immunity. If you go STR based then craft armor is better than craft weapons, and in any case if your level 60 feat is brutal throw we have a problem.
