If you have to name one thing that is the most annoying about the Legendary PvE Armors, Legendary Runes and Legendary Sigils it is very likely you would name the Provisioner Tokens. Going through all those maps to buy all the daily tokens can be really annoying.

Luckily there is frenkey_Provisioner to take that burden off your shoulders. After setting it up it and having the items in your inventory it can automatically exchange all the tokens for you! If you don't have the items yet and need to craft them you can easily generate a link for GW2 Efficiency to see what items you need etc. Just select the items you want to use in the Map Tabs, set a craft amount and hit “Generate Crafting”.

Select the items you want to trade for tokens and toggle the Auto Mode. Nothing else to do! If you don't want to run it fully automatic you can manually go through the vendors and let the tool move to the merchants or buy the items once reached.
