Malphite Passive

I'm not a fan of minion targeting to begin with, they seem to sometimes just target random things and change targets awkwardly. But when it comes to Malph's passive, it's super annoying. Especially in lanes where you're getting poked down and need to be able to back off sometimes, it's very costly to have the random cannon minion just decide to attack you when you've avoided damage for nearly 10 seconds, only to realize you've lost farm to gain shield and you don't get it anyways. It's also annoying to have traded, win or not, and have these little caster minion autos chasing you while you run away and keep your passive off for an extra 2-3 seconds. Maybe he's in a place Riot is happy with, but changing his passive to ignore minion damage for the reset would be a great minor buff in my opinion. Maybe minions ignoring the shield all together, as in not damaging it either, is the way to do it. I'd just love to not have minions reset the timer after I've carefully avoided champion damage.
