Most of the legacies are a simple pick;
bow- crit multipliers both, power reduce if you struggle with power management.
melee- needfull haste is a must, beneath notice can help, i use the agile rejoiner heal one too.
HS legacy sounds tempting and if you purely solo its fine, just you only should really use it to open a fight and you shouldn't use this to open a fight in a group unless you can solo the mob ie. often wont get used at all.
I would look at the lorebook section on leg items there's a big list of them and the choices are often just common sense and picking up enough items to farm them from.
