Let's not forget that in some ways, RIOT has come to an understanding that simply adding a mana cost to limit a champion's playstyle is neither intriguing nor intuitive. For mages it can be understandable, but for a champion like Gangplank who has a unique style, having a mana cost on his battle setup ability would heavily burden how he functions. Balancing mana costs between Q and W to make way for a cost on E wouldn't help either.

Instead, Powder Kegs have a semi-long recharge time (at least early on), don't have overlapping damage, cannot be instantly blown and have other traits that already hinders it from having too much power. Even if RITO decided to mana cost, they would likely not make it expensive at all, for the aforementioned reasons about: the ability's potential damage is gated by certain criterias already.
