How are you not seeing that as a meaningful distinction? Your barbarian rolls 15 for initiative. The surprised knight rolls 16 for initiative.
The surprised knight can now use his parry reaction on round one when he is surprised. He has his turn on initiative count 16 of round 1, can't take any actions or movement, and then his turn ends. Next goes the barbarian who attacks him on initiative count 15, and our knight parries his attack.
If the surprised Knight had rolled a 14 or less for initiative, he could not parry the barbarians attack on round one when he is surprised.
That
assumes he's successful. First on that A: he rolls higher and B: the Barbarian hits and C: the
NPC Knight successful parries.
If A is false then your whole argument goes out the window as it
doesn't matter. If B is false then A doesn't matter because there's no need. If C is false then we just went through the whole situation for exactly
nothing except to make the only
player in the situation, the Barbarian, drag out his action and force the DM to go through a bunch of extra steps to arrive at the same conclusion.
I don't like doing extra work just because the rules say I should. I have enough work on my plate. It's IMO, faster, easier and more exciting to let the Barbarian have his lucky shot and the move on.
You are arbitrarily and for absolutely no reason depriving characters of their ability to take reactions.
Bolded and snipped because this is the only point that matters: I'm not depriving
anyone except myself (since the Knight is an NPC and therefore under my control) of anything. So I'd appreciate it if you take the outrage down a notch because I'm not burning a
player's sheet and it certainly isn't
you at the table. So chill man.
And I mean it's not like you're saving any time because you're going to have everyone roll initiative after the attack anyway.
I'm saving time by not having to resolve potentially an entire party of turns before the Barbarian gets his surprise. There's not a 100% chance of a fight anyway.
I mean it's bad enough in this example that you would even let the barbarian attack with surprise. If I was escorting some NPC Prisoners out of a dungeon and you had them attack me with surprise, I would leave your game.
Great, bye! Works fine for me and the people I play with.
I mean I just sit there and get attacked while you grin at me over the dungeon master screen and there is not a thing I can do about it.
This happens sometimes. I've been on both sides of this. If you're going to walk 'cause 30 seconds of the game makes you unhappy, by all means,
WALK. I haven't the time or patience for that sort of behavior.
But, we're not playing together, so seriously you should take how
I DM
my table
less personally. Since you are not
at my table and you are not playing with me, the idea that you would "walk from game" is frankly meaningless grandstanding.
