As per @PhilthyPhilPhD 's suggestion I've made a new poll:

https://www.surveymonkey.com/r/YTP8RNS

Unlike the old poll you can now rank several factions according to your level of interest. This should give us a much better idea of the most desired factions since many people want more than one.

If you don't know or care about a faction just mark it as "Indifferent". You can change your answers after you submit them.

EDIT

Results can be found here - https://www.gamereplays.org/dawnofwar3/portals.php?show=page&name=dawnofwar3-next-faction-survey-results - Gorb
