Ahri compared to Swain
Both champions have similar Q and E, and vastly different ultimates. Ahri is almost always glass cannon / squishy, while Swain can go ROA and still be on equal footing in damage. Swain gets stronger the bigger the team fight; his snare and Q do AOE, on top of his Ult. Ahri is supposed to be the same way, but her kit just feels very lack luster. And if good players are surrounding the guy charmed.. you're forced to ult away.
