The Sisters of the Burning Blade

A look into the force that is going to be arrayed in my new 5th edition 2000pt Sister of Battle list.

Canoness - Blsd Wpn, Clk StAsp, Inferno Pis, BoSL
Retinue, VSS - Combi-flamer, 4 x Celestians w/ Melta, Hvy Flamer, and mounted in Immolater EA/Smoke/Twin linked Hvy Flamers
SoB Sqd 1 - 10 Sisters, Flamer, Hvy Flamer, VSS - BoSL - mounted in Rhino - Smoke/EA
SoB Sqd 2 - 10 Sisters, Flamer, Hvy Flamer, VSS - BoSL- mounted in Rhino - Smoke/EA
SoB Sqd 3 - 10 Sisters, Flamer, Hvy Flamer, VSS - BoSL - mounted in Rhino - Smoke/EA
SoB Sqd 4 - 10 Sisters, Melta Gun x 2, VSS - BoSL- mounted in Rhino - Smoke/EA
Inquisitorial Storm Troopers - 5 men, plasma rifle x 2 - mounted in Chimera
Exorcist 1 - EA
Exorcist 2 - EA
Seraphim - 9 Sera jumpacks , Flamer x 2, VSS - BoSL - (Can deep strike now, yummy)
Celestians - 6 sisters, melta x 2 - mounted in Immolater - EA/Smoke/Twin linked Hvy Flamers

Here is where I need to start considering options - maybe swap out for the Celestians

Retributors - 6 sisters, 4 HB (very fond of this unit)
Celestians - 6 sisters, melta x 2 - mounted in Immolater - EA/Smoke/Twin linked Hvy Flamers (for the extra annoyance of fielding another tank and being able to pop heavies w/ meltas)
Armor Fist Squads x 2 and Leman Russ Tank x 1 (I love taking the Russ, hopefully we might be mentioned in the IG codex as allies, but I do not see WH being able to use IG special rules, it would be too sweet)
