ok, so one of the reasons i love supporting in dota is being able to teleport to a tower and turn around a gank, where they thought they'd be able to kill my carry but instead i kill them...
how do i do something like this in league? as far as i can tell, you can't tp to towers/turrets.. so i'm a little confused how the early game is supposed to work.
You can TP, but only with the TP spell. This was a big adjustment for me. Turning around ganks in League is much more about predictive movement and "right place, right time" than an immediate turnaround across the map.
Also it's about knowing when to roam, since your map movement isn't quite as free (can't just buy a bunch of scrolls and TP all willy-nilly).
