Gangplank's barrel nerf doesn't feel good

Last patch, GP's max charges on his barrels was nerfed from 2/3/4/5 to 3 at all levels. 90% of the time, you need two barrels to do something with them, so 3 barrels late game doesn't feel good at ALL, because you use 2 barrels for a combo and you're stuck with just one for the next 7-10 seconds. Instead of making the max 3 at all ranks, can we make it 2/3/4 at levels 1/7/13? That way, he has 4 barrels for two combos before it goes on cooldown.
