Yorick, @Riot: Quality of Life
The quality of life changes have been most welcome, with the capability to bring my mistwalkers and Maiden with me much more effectively the game feels much more dynamic. Returning the upcoming change of summoning Maiden in a lane to push it sounds like it could be most useful as well if only she wasn't dying to the tower before putting adequate pressure on the enemy team to take care of her since so much of Yorick's strength is tied to her. In short, the cost of using Maiden to push is too high since she will not cause enough pressure to force a response from the enemy team, better to have her available for teamfights right now.
Yorick still feels undertuned however to me, his attack animation feel sluggish, the response time of his mistwalkers when hopping to their target is so slow that enemies walking away from them never even get tagged by them. The punishment for missing Mourning Mist means doing no damage at all and is generally easily avoided by champions with any mobility.
The biggest QoL changes I would like to see on Yorick is more reliable mistwalker control. Yorick's Last Rites feels like it should mark the target he hits with it, making all Mistwalkers focus that target.
Also, would it be possible to have them not suicide by running out of his range, if they are not on marked targets it feels like they should stop attacking if Yorick goes out of range and move back to him. This just makes the strategy of kiting them away not as good, and means the enemy has to actually clear them, which is easy enough since they do not focus champions over minions anyhow. The current range is pretty far though, so making them leashed at a shorter distance would keep him from safely pushing the lane over 1k range away.
