May I just nudge your attention back up towards the "Lore bore" rule.

I take your point but I've seen too many decent 40k threads go straight down the drain or get indefinitely held up because of needless OC lore points and counter points.

In place of a Vindicare might I recommend a Storm Trooper or Catachan sniper?
You could still be a highly trained professional more in keeping with the groups current level.
