Honestly, I'd say they should ease up a bit. They've shown with the 2 new races this expansion that time constraints are very real. I'd like to see them perhaps add the other 2 genders and polish up the existing races for 6.0. Then one new well polished race for 7.0.

There are a ton of interesting races in the FF series but I wouldn't want them to tumble out a mass of half-finished races.
