Here's yet another unecissary addon that shouts out your rank / renown level when leveling up*
*now with career icon and renown title
On level or Renown gain:
Spoiler:
Use /ding to shout out manually
1.2: added /ding and disabled the renown shout, since it seems that the client/server updates the renown level everytime you zone
1.2.1: small dirty fix for the anouncing while zoning, renabled the renown shout
1.3: Rewrote the addon to now only using 10 lines of code
