Lately the vindicare's been ruining my plans with his shell breaker shot (takes away my invulnerable saves permanently!), AP1 sniping, his ability to pick who dies and turbo pen shot (3D6 armour pen and wounds) and the calidus has been a death blow with that high WS, I and A and ctan phase sword thing not to mention the "whisper in the ear" rule. They're also being hard to kill with the 4+ dodge for the calidus and the stealth rule for the vindicare (which usually means that it's a 3+ cover).
There are alot of players out there who have them so I'm really hiting the panic button now.
