I am looking forward to the tank updates in competitive play
Just imagine all the new moments that will arise from this
catching stragglers with saplings placed in advance as mines, getting off massive flanks with his ultimate, or absolutely wrecking a Cassiopeia by making the most of his passive, a spirit visage, and an adaptive helm.
Doing his usual awesome things, but now with even more goo! Fast revives are going to make him even more impactful later, and his ultimate is cool as hell (especially if combo'd with a Rumble ult and Nami bubble waiting at the final destination)
seeing the rise of burly melee comps going absolutely HAM. Braum+Sej would be absolutely nasty and I love it. Hell, I'd not be surprised to see her paired with Renekton, Yi, Tryndamere, or Mordekaiser.
