To everyone complaining abotu the balance of edge of night.
maybe it would seem more balanced if you actually played around it correctly.
yes the item makes you need to rethink how you play, that is A-Ok, plenty of items do that, banshees has practically the same effect, warmogs makes you need to go harder after every fight, zhonya's makes you need to either conserve burst or kill target while they are cced.
Now stop blowing your only cc into a target with a spell shield, and start popping the shield and then peeling. good job, you can now deal with someone with a spell shield.
