Can Riot please fix tanks already?

I just played a game as Orianna vs Maokai mid, and have to say, it was one of the worst mid-lane experiences I'd ever had. Lvl 2 he could already get me to half health when he engaged on me, and i couldn't do jack shit. If i tried to poke him, I'd go oom and he'd sustain it back up, if i aa'd him, he'd engage on me and i'd lose the trade. The only reasonable option would be to go under turret and wait until he gets strong enough so he can turret dive me without any problems. Without jungle help, I seriously don't know how i could play that lane, and, like this game, I can't expect my non-premade jungler to camp my lane.

I can finally understand why top laners are complaining so much, because this was seriously bullshit. They out damage you, they scale well, they will outtrade you. I seriously don't know how i should've played that lane.

Why is it that as a mid-lane squishy mage, I'd rather play against Zed, Fizz or some other assassin, than play against a bloody Maokai. At least when Zed tower dives me, if i land my ult i can pretty much guarantee he will die, unlike Maokai, who just shrugged it off, traded with me under my tower and left with over half his hp while leaving me at 25%.

If you think I'm just being salty, then please give me some advice as to how to play that lane, preferably how to play it solo (Without the help of my jungler, since i can't expect that every game). Thanks.
