Simple suggestion to allow the abyssal echoes node which grants health on echo to instead grand ward. Small change but it would allow the sentinel access to skill related ward generation which would scale down for single target so as not to break the game as well as make abyssal echoes an appealing skill to use in a build again. Ward is one of the most interesting mechanics in the game currently to build around and diversifying options while maintaining balance and individual identity is healthy for a game.
Also, making Tempest Strike the Primalist’s only means of active mana regeneration and not allowing the skill to scale with attack speed is terrible design synergy and feels bad to play. My two cents for the moment.
