I think they used to be somewhat like that actually...I remember a time when their elites were 4/4 or something along those lines (specs were 5/0 and 0/4 for them I believe)...but they had +20% population bonus? It was quite high...and I thought that was definitely a boost to the game variety.
Honestly, those are good suggestions and I think that when we all work together to comment on each other's suggestions, hopefully that encourages some of these changes to be considered.
So I adjusted Halfling Pop Bonus to +15% and their elites to 6/6, and gave Dwarf 4/8 Elites...which makes them a super tank...
