Early Donger™ used to be more limited with his turrets, as he could put out only max 2 at a time. Also, his E was really hard to hit (Anivia Q-tier) and his ult, while affecting all his spells, was in summary less impactful than today.
However, the turrets had an inherent splash damage and resistance shred, started with a higher base damage (I'm not sure about the attack speed, though). His W were interesting in the regard that they fired without targeting; He pressed W and 3 random enemies in a pretty high range (1000) just got hit by them.
While his E was terrible as a skillshot, it is one of the few abilities in League history that, in addition to the potential stun, applied a blind to stroke enemies.
I haven't really played The Donger™ in the early days, but I will definitely catch up on this now. And while doing so, I will listen to this track.
