Nerf Superminions or buff turrets

As the title states, it feels so difficult to kill a super minion. For example, you can four hit a turret with Veigar, but you need to drop an entire combo on that one minion to kill it. They're way too effective at tanking+dealing damage to our flimsy turrets, and pretty much no one but the ADC really does anything to the minion. They chunk away at your turret's hp, and this is especially frustrating if you're the support, playing something like Braum and desperately defending your last nexus turret while the rest of your team is chasing someone across half the map. The super minion will literally murder your turret's arse as you feebly auto attack it with your feeble 94.1 AD. Your entire combo does maybe a quarter of it's health, and that's it. Despite your best efforts, your nexus turret still blows up. Very frustrating in low elos when your team is extremely kill greedy and doesn't have any map awareness, leaving supports to clear waves to prevent the minions from blowing up your nexus. The sense of futility I experience as I realize that not even my ult will save turret and that I can't even kill a stupid minion is so infuriating.
