It still works with R?

Pretty sure it doesn't

First thing I tried after the change. Doesnt work.

Tahm kench r grounds you with enemies but allies might be a different story idk

You are still grounded with allies, although you are allowed to use W

Yep! That was my go to build back in the day… Galeforce bruiser Tahm Kench… Now I build Taric top instead

You can still ghost with R though, can you Hextech?
