Invisibility & Stealth are 100% Broken
Ever since the changes to wards, stealth and invis have been completely broken. Riot has taken away the fundamental part of having wards with their rework of invis/stealth, and the introduction of items like Duskblade into the game (the absolute most broken item in the game..you can literally one shot ANY WARD as many times as you want). The game has become a game that takes no skill, and merely building or playing whoever is currently OP.
is still op even with her nerf.
