Can you nerf Druid Mechatung + Poison Seeds?

Disgusting strat. Many of them around these days and you cant do anything unless you are an enrage team and kill the druid in turn 4/5.

Poison Seeds needs a nerf long ago. It kills minions even though they are immune. So If they got the immune buff how can they be destroyed the same by Poison Seeds?. It doesnt even make any sense. And it does.
