New idea for Teemo's passive

I really don't like what riot did to Teemo's passive attack speed bonus when he get out of stealth at the early levels in my opinion its just too low. All the other stuff they added for his passive are cool but the attack speed nerf was not cool. I think that the idea of his passive was to get those early stealth attacks to that enemy toplaner or midlaner who didn't know where you were and then when the enemy champ got close you attacked him with that awesome attack speed and took lots of health away from him. But in the late game you don't use that passive too much coz your job is to shroom the important places like baron and the big dragon and the places where you think you are going to be fighting team fights. And the Teemo buffs that are ont the PBE right now are awesome especially the arm time reduce from 1.5 s to 1.0 s is super awesome and i am really happy about that i think many other Teemo player's are happy about that buff too. So my idea is that you remove the attack speed bonus from his passive he when out of stealth but now Teemo gains bonus magic damage on his next basic attack when he gets out of stealth or maybe bonus attack damage or true damage like something of bonus 15-20 damage at level 1 and it would increase as Teemo gains more levels. Now when Teemo goes stealth in late game and an enemy champ comes near. Teemo would be able to land 1 strong auto on the enemy and then back off if the enemy team is near him or then fight him and maybe destroy that enemy. Well this is just my opinion and i would like to hear your ideas for Teemo's passive :D. Sorry for my bad english.
