One thing that often arises is the idea that the 40k games should be more deadly.
The other thing receiving much hate is the vindicare dodging everything.
I have one idea that can do both. Or at least make fights potentielly last longer while nefing the vindicare.
That idea is incorporating an increasing check penalty to characteristic checks thats resets at the start of the round.
So you get a cummulative penalty of -10 to ckecks after the first time you checked on that characteristic each round.
The following HR is best used with the BC rules for lightning attack and such.
Example:
A Vindicare is being shot at by 5 guys, all of them are lucky and succeed at their to hit roll.
When the assassin dodged the first he has his full dodge of say 100.
At the second dodge he gets his first -10 penalty and dodges at 90% chance.
The third attack is dodged at 90% chance and so on, with the fifth and last attack "only" has 60% left.
If that Vindicare tried to use stealth later that turn (however he'd manage to come later than those 5 guys) he'd do so at -50% penalty, because it is again agility he'd be using.
For shooting one of the attackers he'd not get a penalty, because he's not used BS yet.
Example 2:
A Khornite champion is in melee with 3 guardsmen. One of them gets to go before the Khornite, hitting him with his combatknife.
If the Champion decides to parry that blow he will have a -10 penalty on his attack because both, melee attack and parry use the BS characteristic.
Should he instead dodge he could attack at full potential.
