I’m currently running my mesmer with the duelling grandmaster trait Harmonious Mantras, which gives one extra charge to mantras.
However I noticed that the extra 3rd charge often simply disappears for no reason, leaving me with two charges only. It seems to happen usually in cases including but not limited to after I take a waypoint far enough for the load screen to appear (on the same map). This happens far too often to shrug it off, making a joke out of a grandmaster trait.
Also, please give us a method to recharge our mantras to maximum charges while there are still charges left. It is utterly pointless to make people choose between running with only one charge left or risk getting into a fight with no charges by expunging it in hopes the cooldown will be up by the next fight. Make it a full recharge animation per charge, add a proportionate cooldown, make it give self vulnerability, make it out of combat only, add a timer that automatically adds one charge every full cooldown if you take the grandmaster trait, I don’t care; there needs to be a method to “top-up”.
I’ve noticed this, too. Usually it happens when you transform into anything else (think transforming tonics) or when you go down. Kinda annoying because it defeats the whole purpose of this grandmaster trait. I’m going to venture a guess and say that anytime your util bar changes, it affects your mantras.
