[Open] Where is my Assist xp

[Julia.]

You got the XP for the kill (which happend after you died but you still got the kill and therefore the killing XP) but no assisst-XP as you were dead.

I had that happen multiple times when I died peeking and killed an archer/Xbow which killed me and I killed him (or some random other one).

Its pretty simple: once dead you dont get assisst-XP, but any kill gives you your killing-XP.
