If you replaced Shen's ultimate you would never know he was the same champ from pre-rework.
Different build path, different passive, different Q with a different passive that removed his health restore mechanic, weird power budget for his W that's useless against half the champions in the game, and now he plays more like some kind of duelist rather than a hypertank. Laning phase doesn't even play remotely similar.
You kept nothing from the original champion other than his taunt and ult. How is this considered a "rework?"
