Trundle's Pillar Shouldn't Affect Same Team

I have been 'trolled' so hard in many of my matches as a result of a teammate who would play as Trundle and use his pillar to stop teleports to base, block the way in the jungle so the enemy team would kill the poor soul, and even getting stuck in a wall. The people who are doing this are doing this on purpose, of course hence the 'trolled' comment prior. I know it won't stop the trolls, but it still shouldn't affect teammates in such a manner.
