A Warrior can only charge one Warrior? Is that something GCE stipulates? (Not a rhetorical question, I'm ill, remind me, please!)
Can only charge one: As far as i can tell from https://gce.gorkamorka.co.uk/gce-core-rules/#charging
And:Note that Warriors may only Charge the nearest enemy Warrior.
They need to pick A target to charge, no mentions of placing in contact with others than the target.Assuming your Warrior can reach their Target, place the Models so that both of their bases are touching or as close to as is practically possible.
The Orks then charge in, how do we unpick it?
The outnumbering player could decide that the match ups are:
1:6
2:7
3, 4, 5: 8
Or they could decide:
1, 2: 6
3:7
4, 5: 8
There's probably other combos but I can't be bothered to be exhaustive as I think the setup is clear enough to progress the discussion.
Okay, so RAI the engagement shuffle happens when attackers are outnumbering defenders and "close enough".
1 could only fight 6.
4+5 could only fight 8.
Hmm, so ill probably need to make a per defender "for sure pool" consisting of attackers without options and another per defender "possible pool" of attackers that are within half an inch or so.
Attackers with options would get listed and when one is selected, its defender "for sure pool" options would pop up.
Clicking an option would allocate them into the "for sure pool" of their choice.
Repat for all attackers with options.
Highlight empty defender "for sure pools" and attackers that may be allocated to them before allowing assignment confirmation.
Then allow for running the regular one on one combat or the multiple on one mechanic ive already set up with the attackers from for sure pools against its owning defenders, as applicable.
I think thats a systematic enough way of breaking it down for a computer to understand.
