For pve Mantra's are fine. even like them more. since befor path you never played with the 3th charge. so since now you got 1 more charge it's a buff. but pvp I can understand you need that stronger last push to kill people. so there it might be weaker no idea about that. But the Heal mantra an 20 a 30% buff while be nice. is idd a bit weak overall.
