let's talk about terrain

So with new Yorick we have yet another skill that creates terrain, I think the way it works on Yorick is quite awesome but when looking back at the other skills that has this effect, you can't help but think that some of them are pretty outdated.

I'm mainly talking about 's wall, honestly, I can't find a reason for this wall to trap teammates at times, I guess it adds a layer of difficulty to the spell but in reality this is the most trolly skill that has ever grasped league of legends, going back to season 1, an user caller Mclaren made this pretty clear by making a video that was even banned on these forums.

This quality isn't true on new Yorick since allies can go through, also allows allies to go through, on the other hand doesn't let anyone go through but given his power quota I think it's ok; on 's ult is also understandable that allies can't pass through given the power budget of the skill.

but ? why is she allowed to trap teammates the way she does on a not so high cooldown basis? thoughts?
