Now if i could hope for a new skill for mnk, it would be something like a meditation ability. It would only be accessible outside of combat and would give you GL3, so that you wouldnt need to ramp up at the start of a battle. Would fit the theme of monks very well too.

Pondering on that idea they could alternatively also give it a long cast time, say 6-8 seconds and make it usable IN combat. This would solve both the ramping up issue at the start as well as the issue with breaks in battle (you could just meditate while waiting for new enemies to spawn). The long cast time also means that you cant just get GL3 for free, since just pummeling your way back to max stacks would most likely still be better than not attacking for 8 seconds.
