Don't think it's possible to make spirit Graves viable without her being busted

This kit has such an incredibly fucking massive ease of use it's mind boggling, the 1 targets enemies for you, has crazy damage and will keep targeting stuff out of your line of sight, you can light melee the skulls but a skillful graves will keep track of that and get right into your face making you guess if she will parry or not, the 2 is very generous and can be placed behind the enemy giving graves a lockdown ability, will reward you with 2 ghouls regardless you hit your enemy with it or not, the 3 is a passive connected to your autoaim gun, the ult is quite literally the most brainlessly easy thing to use, pop it in your backline, pop it infront of you, doesn't matter they can't interact with it unless they're willing to play the danger game of "will i hit these 2 heavy melees before the graves melts me", hell you don't even have to save it for a teamfight just put this shit on the inactive lane and watch the ghouls help out troopers destroy the objectives

I am not against a character being viable but there should be a balancing limit to how strong a characters kit can get compared to how easy to use it is
