Heimer nerfs

I'm not sure if this has gone live yet but on the pbe heimer has become a shittier cannon minion. Master yi got the biggest buff in the game with the new masteries, yasuo also greatly benefits from them, and heimerdinger, well... I played a game heimer vs yasuo mid, playing like a god, I could always engage or disengage when i wanted, and i never got hit with a yasuo ult the whole game, here's the problem, despite hitting every ability perfectly, i did no damage, the turrets are on a huge cooldown and their stats have recieved a huge nerf, you can have one at a time at level 1 q and 2 at level 5 q, but if you wanna wait 3 minutes you can set up a third. All of his abilities have had their base damage, ap ratios, and usefulness nerfed. I don't expect anything from the riot games balance team, i've long since accepted their incompetence, but this is a whole new level of unnecessary, increasing his mana costs would have made him perfectly balanced. Now he's not even good enough to be trash tier.
