for example a strength 5 vs strength 8:
38,5% against 61,5% hit chance
15,9 damage against 25,2 damage:
should the strength 5 unit get a lucky streak and hit you 7 times without you hiting it 4 times it would win, this would happen with a 4,4% chance.
With 1000 hits it would need 64 hits against 40.
This would happen with a 2,22*10^-5% chance
This would result in following (unless i have overseen something):
longer combat calculations -> thats bad (but i dont know how much longer it could take forever or only a second for 1000 combats)
A stronger healthy unit would win with a much higher percantage against a single enemy
However it would be much more likly to get at least some damage:
0 hits before 4 hits: 14,3% chance in this scenario.
0 hits before 40 hits: 3,6*10^-7% chance in this scenario. ->very unlikly
If you dont heal your strong units its more likly to die after more battles since you would remain with less Hp (in %) after each battle
Average HP left if wins: 66.32 /100 66,32%
Average HP left if wins: 625 / 1000 62,5%[/SPOILER]
short summary for lazy readers:
Should units have 1000 it would resulting in following:
Attacking a single strong unit with one weak one has less changes to suceed
Attacking a single strong unit with a swarm of weak one has higher changes to suceed
