@Riot: Currently Teemo is a pointless champ

So I have been playing a lot of Teemo lately but he feels lackluster and pointless to pick. I have 5 major frustrations when playing him.

1 AA-range His AA-range is one of the lowest in the game for a ranged champ at 500. Given how squishy he is and the fact he can't protect himself from abilities I don't understand this. He is supposed to counter adc's but he doesn't have the range to trade with them. Also most of the toplaners can all-in him every time he tries to AA someone or even farm.

2 Clarity on his blind I shouldn't have to learn which ability and which ability is not affected by his blind. Whenever I see attacks on hit or empowered AA's by intuition I expect Blind to counter them but a lot of the times this is not true. Last game I had to find out the hard way Luciens passive is not countered by blind. How stupid is that. Also whenever I blind and adc I usually get hit first before he is blinded and kinda making it pointless for me to trade.

3 Shroom time The most iconic and unique skill of Teemo: His mushrooms. They offer some quite unique strategic choices, zone potential, kill potential etc but their time on the battlefield is just too low. I hardly have more than 6 shrooms on the map at any given time and they suffer another problem.

4 Red Trinket It took minutes to shroom an entire area just so they could get deleted in seconds by a guy with upgraded Red Trinket and nullify the main reason to ever pick Teemo. Doesn't seem fair.

5 Scuttler The Rivercrab has made it near impossible for Teemo to successfully shroom objectives.

So after playing him a lot of games I really don't see a reason to pick him anymore.
