what races do you find the most cool/fun mechanically?

Does heavy armor or similar things even slow you done in water as a water genasi? I can't find anything that says no to that in the book. Or yes for that matter.

Short answer because I'm tired. From what the book says, generally speaking, if you have a swim speed then you traverse water as if you were on dry land (and had a fly speed technically as you move in 3d).

Now if you don't have the proper str to wear the heavy armor then you will be restricted but that isn't due to swimming.
