If you're a purist and your only contribution is to say they are shit; move along, move along.
If you're not, what do people think about the mixed race options as they stand and, more importantly, what can be done to improve them?
For me, I need mixed (and custom teams) to have access to marketplace. Custom especially. No point creating amusing broken stars if you can't then draft them into your private league.
Marketplace was made for mixed teams.
I suspect exploitation may be a reason why this has been banned (i.e. create a player, move them to your 'genuine' team and bung that team in a league) but I'm sure this can be dealt with or monitored...
I'd introduce "dislike" from 2nd edition and use "animosity" more to restrict killer combinations.
I'd ban certain combinations (Dwarfs and elves, Dark Elves and other elves for example).
I'd cap big guys and specialist positionals like war dancers, beserkers, secret weapons, etc. although this would need some thought.
I'd remove Dark Elves from the Elven collection as it's stupid.
I'd let Flings and Zons play together (with female fling bodies!).
I'd be tempted to make you pick a "core" race and then let you buy slots (up to, say, 4 for normal and 6 for stunties) for the other races in that collection, with each slot adding a % uplift to the non-core player's cost. Bring in diversity but hopefully offset the min/max brigade - or at least limit it to hard core losers rather than casual ones...
Anyway, these ideas are intended to stimulate debate. Any thoughts?
