Holy **** !
I was a dumb idiot... i was level 12 and rank 66, so actually one rank "into" level 14.
Since i saw my rank wasnt a multiple of 5 i assumed... wrongly... that i couldn't be capped.
My mistake, "bigly" ...
So, i apologize to standing stone (even tho, no answer on a ticket for 3 weeks is still bad imho).
And to xCataluna for my ridiculous answer starting with "i know quite well how xp cap work" ... lol
"ridiculness doesnt kill" - hopefully since im still there

(french saying translation)
Forget that post, all is fine, im just an idiot.
