This doesn't appear to tally in a lot of PvP matches... I've only noticed it during the "Fight of the Fowls" event that is currently active but it's clearly an issue outside of this event also.
In my PvP campaign I have 234 captures whereas for the achievement I only have 102 so something isn't adding up... the PvP campaign is relatively new also so my achievement figure should be higher than 234
In comparison my PvP campaign win figure is 24 whereas the "Proven Challenger" achievement has me at 36 from pre campaign wins...
