Irelia will likely be nerfed soon
So many top lane champions were nerfed (Jax, Ryze, Shyvana, etc) this year, and Irelia is an absolute terror at all stages of the game. With passive lifesteal, free tenacity, true damage, and a gap closer that resets on kill her kit literally has everything. All you need is triforce and no one can duel you (unless they're super fed). Irelia never asked for any of this though. She's simply become more viable due to other champs being nerfed. Of course, knowing Morello, we all know what will happen to poor Irelia.
