3 100% neccesary Yorick buffs

1. Make ult cooldown start at summon
2. Allow yorick and maiden if near each other to both have 4 ghouls totaling 8 instead of current 4
3. Make gravestones last a lot longer even when yorick leaves their vicinity so he can build ''graveyards'' so he can store some ghouls for later use, 10 minutes similar to bard chimes sounds fair

Yoricks ghouls are pretty suicidal and he has no control over them besides E And while he is decently strong with them he is pretty weak without any ghouls. His ghouls/maiden are very easily killed since they have no armor or mr. This puts yorick in a tough spot as in many cases a simple aoe like tiamat or sunfire can wipe out his ghouls way too effective, not to mention any aoe abilties. Some people have argued to boost his numbers like his sustain, even i have done so by asking for tougher ghouls/maiden, but why not instead just give him better and more access to ghouls/maiden. this way his numbers can stay the same and the ghouls keep their easy counterplay without leaving yorick all alone after a single arcane smash or broken wings. He could build a small graveyard so he can summon more then 1 wave of ghouls. and this also leaves him the opportunity to safe some graves so he can summon a few ghouls before grouping up with his team to contest an objective

Meanwhile maiden turns into a better splitpush threat as it can be send out a little more often, and yorick will be rewarded for managing to keep her alive by drawing aggro himself and stall his enemies from pursuing maiden and killing it.
