If she have normal nade like csgo nade i dont think its overpower, the 2nd phase of her nade the annoying one, if you go behind cover its still hit you somehow
two sage walls would be sage, her defensive capabilities are already some of the best in the game as it is. mobile slows that have a huge radius and duration that stop execs rly well? sounds pretty good to me. the healing maybe needs a buff but thats literally it.
