Sellswords trilogy

I'm in a reading spree :).
I'm talking about the last books of the "trilogy" because the first one doesn't have any connection with these 2 (but still it's a trilogy).
"The promise of the witch king" reads very much like the story of a second rate hack and lash RPG : assemble party, locate evil, kick ass. That's all .
"Road of the patriarh" is just simply....pointless. Story wise there isn't any point for that book to exist.
If Salvatore wants to "keep" Jarlaxe and Antreri as valid characters he must do waaaay better than this "Sellswords" trilogy.
