IDK how I feel about your class ranking, IMO I'd go
S: Sunsinger
A+: Gunslinger
A: Striker, Bladedancer
B+: Voidwalker
B: Defender
Striker and Bladedancer have more options against serious players, but Golden Gun is just so good in this format. Sunsinger gets first for being the only class to have a great super, melee, and grenade (Gunslinger doesn't have a good melee, Striker is missing melee/grenade, and Bladedancer's Melee is situational).
I'm a hunter first and foremost. I ran Gunslinger in the first week and shifted to Bladedancer for week 2. Gunslinger definitely has the superior super for the format, but Arcbolt grenades are right up there with Firebolt grenades for best in the game (good players just will not get hit by tripmines) and Bladedancer's super is decent (I got a triple kill off of one Razor's Edge somehow, how I wish I had a recording setup).
Fist of Havoc beats out just about every other super in the game, Bubble loses out to just about every other super in the game.
One thing I noticed that had changed from last week was just how narrow the weapons used were. More often than not everyone on the enemy team used Thorn. Generally speaking, our team was two of us with Thorn and snipers, and I covered our flank/flanked with The Last Word and a shotgun (Matador 64). We ended up going 8-1 because I got disconnected midway through a game.
IMO Primary weapon tierlist would go something like this
S: Thorn, TLW
A: Red Death, Hawkmoon (am Xbone, don't have experience with)
B. The Messenger, MIDA
C. Other Legendary Pulse Rifles
D. Everything else
E. Legendary Assault Rifles
