Anyone else think Teemo feels weaker now

The passive was awesome to have for him and I love it but his shrooms are just so weak now. A 5 minute duration for a shroom is nothing to teemo he needs them to be 10 minutes like before. Its so hard to actually establish his global pressure and contest objectives with his shrooms now. I at first thought throwing the shrooms would be awesome but when I found out they crippled his duration on them it just feels now he is a shadow of his former self now. The recharge time it takes for Teemo to gather a shroom takes so long I can only have up to like 6 or 7 shrooms on the map that's insanely small for teemo. Either make it to where he collects shrooms faster or bring back the old duration of his shrooms to 10 minutes.
