You can make a macro with the line: /levelsync and put this on a bar so that you can bind a hotkey to it.
Considering how many people will farm Fates for the Relic upgrade I just wanted to give you guys this little tip so you don't have to always press the Button itself. Hope it helps, I found it pretty useful.
Ps: Im also wearing my weapon only to save repair costs as the durability seems to drop rather fast. You don't really need an armor for fate grinding anyway :)
