Gragas problem was that he was AP. When you are an AD bruiser, you will never get destructive power and tankiness, unless you build both. But when you are AP you can get both simply due to the nature of AP items. Gragas was a problem because he was hard to take down, and because his ulti wasnt being used for the utility, but for the dmg. Also his Q, which had high dmg to compensate its incredibly dificulty to hit in lane, was stupidly easy to hit in teamfights, resulting in a super strong nearly undodgeable 190% AP AOEplus high base. Most times this alone can kill squishies.
