Dwarves need to "discover" their female counterparts so all the women who complain that they can't play a male toon will actually roll one & play it :)
As far as Vampires & Were-types? meh... RW could give us a Holloween event where we can get some transformation pots like the Gingerbread man one ( +20% stam )... but they could be a little more complex...
ie,
Vampire Transform Pot:
Duration: 3600 seconds
Effect: +5% all stats during daytime; +10% all stats during nighttime; -50% resistance to Light & Fire attacks with a chance to get a Burned debuff for 20 secs where the player receives an additional 20% damage from Light and Fire attacks. Once this debuff occurs, it cannot occur again for 40 seconds.
Lycan Transform Pot:
Duration: 3600 seconds
Effect: +5% to Str, Dex, Stam; -3% to Int, Wis; Player has a 50% chance to resist white hits; When hit, there is a chance that AutoRegen buff will occur for 20 secs where the Player will recover stamina x 5 hp every 5 seconds; once this buff occurs, it cannot occur again for 40 seconds.
Special Effect: When Lycan Transformation is in place and a full moon is up, Str, Dex and Stam are increased +10% and MoonRegen buff will appear for the duration of the transformation. During the MoonRegen buff, Player will recover Stam/3 hp every 2 seconds.
There.. no new classes, just a couple of transform pots.
