I'm not play Sam because it op or anything. It's a jo i'm learning in pve though i'm a bit mainoholic. (Only play alts to mostly try replace main). lol. Sam great at 1v1 other sams... lol. And stopping others from caping points. While the LB can 1hko, it's niche. I might 1hko maybe one out of ten times I use it. Feel good when it does but even in large groups, no one may even hit me.

To the 2nd point. I do wonders on a bard. FL and CC (non ranked). I get those scores too. While bard has some fault, its good. Plus I like the archer feel. It just, I like melee. Been trying to get better. Still hate positionals but they not as bad as I thought.
Of the three melee i'v played in pvp (War, Drg and Sam), I found War the best followed by Drg.While I find Sam more tanky then Drg. Drg feel I do more and they have a better LB. War just a beast..
