I heard on my necro that guardian’s GS skillset have its order changed, so I logged on my level 5 guardian, who just acquired a greatsword and unlocked its first four abilities today, to see what’s going on.
Turns out that 2 is the whirl, 3 is the leap, 4 is the symbol. However, I could not use leap of faith. I press 3 and nothing happens. I could use the whirl or the symbol no problem.
I am fairly sure that I have unlocked leap of faith today before I logged off on my guardian. The UI also shows that I have fully unlocked the first four abilities.
I could, however, use leap of faith in the heart of mists, where all skills are unlocked.
