What if Trundle. ...

I think that has a lot of potential as an idea, but it would need some sort of gating mechanism to prevent someone totally blocking off an escape. Right now Trundle (One of if, not my absolute favorite champ in this game) already excels at zone control, between his Pillar and his Frozen Domain. In the jungle, he can already block off a whole path with one pillar, which is HUGE in team fights. If he got pillars on a sort of ammo system, they would have to have at least a 3 second cool down in between placing one and the next, with maybe a 15 second cool down at max rank. I will say though, that this is a strong instance of "If it ain't broke, don't fix it"; Trundle doesn't need this and it wouldn't really add anything to his gameplay except something that would probably get nerfed.

I can see pinning enemies entirely with this.

Yeah man, In 5v5 that would be a game changer. Too op. lol Great idea though.

I worry they would nerf him if they did this. He has the best raw damage of any tank without needing to build damage. Also I kind of hate anivia's wall. It screws with her allies as much as the enemy. I like that Trundle's Pillar doesn't do that in its current state. My allies are never pissed I placed it.
