human hit box
If you’re in PvP you definitely want to be less noticeable, so yes, size does matter indirectly even if the hitboxes are all the same.

I think they do matter, charr’s have bigger circle highlights so they are easier to hit.
Size doesnt matter sincethe hit box of every race is the same. maybe its difficult to locate a small asura in a big zerg v zerg fight but in tpvp/pve i have no problems.
You also have to keep how noticeable the animations are in mind.
Asura are the only race with an advantage here really, as in the heat of battle it’s difficult to see their animations.
Size doesnt matter sincethe hit box of every race is the same.
This is the valid answer to the original question.
