CarrionCrow: Want my perspective on them?
j0ekerr: I suspect it will be something along the lines of "useless fire obsessed flagellants."
CarrionCrow: It's old business, and old business frigging ALWAYS comes with that masochistic self-injury aspect to it.
Bitch about it, avoid it, eventually cave and buy (or in this case rent) it, suffer through it, hate it, wish death upon it, finally clear it, then never play it again.
j0ekerr: It does have some epic lines.
"METAL BAWKSES THE FEWLS!"
And about every line spouted by Indrick Boreale, the space marine commander, who sounds like a drunken Glasgowian.
I believe everybody was drunk when doing the voice recording.
They're made out of toilet paper, even with the upgrade, and for a bunch of supposedly obsessively faithful murder nuns, their morale breaks like cheap glass to boot when they're up against something like a Chaos Lord with the morale killer item.
You can complete the whole thing with nothing more than normal troops with heavy bolters and melta squads (adding missionaries for infiltrator shitheads), Immolators and Penitent Engines if you get bored and feel like doing melee.
Seraphim are worthless, their only value is krak grenades (which you have to pay for to upgrade), and you'll already have melta squads that also get the grenades with the upgrade.
And yes, melta squads are bullshit. They should be, oh I don't know, FUCKING MELTING PEOPLE, and yet they seem to have had their weapons replaced with "hey we're not trying to kill you so much as fondle your balls until you laugh at us so hard your heart explodes" beams instead. Getting the melta upgrade from the vehicle builder is pretty much essential, every single time, just to try to mitigate their shittiness.
As for their faith powers, I used the blindness power that the canoness gets if you pay for it and the missionary power that increases attack damage. That's it. Everything else just sat there.
Also, their ultimate weapon sucks too. She absorbs damage, but that's about it. I've left her flying ass to fight off a single squad of regular enemy troops, gone off to do other things, then come back to find her still there, chiseling their health away one miniscule shred at a time.
So yeah. You got it right. They're pretty godsdamned useless. Looking forward to playing as a group that sucks less ass.
