A druid's Wild Shape feature specifies the following:
• Your game statistics are replaced by the statistics of the beast, [bla-fu about stuff you retain; resistances are not mentioned]
[...]
• You retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so. However, you can’t use any of your special senses, such as darkvision, unless your new form also has that sense.
Clearly, your resistances are part of your "game statistics". However, they are also clearly a "benefit from your [...] race", and not a special sense.
Logically, it doesn't make a whole lot of sense to me why a wildshaped tiefling, for instance, would retain his fire resistance in wildshaped form.
Is someone able to clarify whether or not you retain your racial* resistances while wildshaped?
*I don't care about class-given resistances. It makes a lot more sense for a raging barbarian or a level 17 war domain cleric to keep his resistances than the racial example given above.
