EOC Glitch?

When I am doing PvM or PvP now, it does not give me any combat xp at all. Not during the kill, not at the end even when I log out.

Is that a glitch ?

 

You only get XP if you are the first person to do damage, and you get it at the end of the kill.

 

Wow, thanks lol. That's made combat slightly harder to gain xp in

 

Actually XP gains has increased if you know what you are doing.

 

And what must we do?

 

He's talking in-general whilst training Slayer, or generally just training combat on monsters from what it sounds like.
