ARAM and Itemization
Why does a game mode that distributes RANDOM champions offer items that target SPECIFIC champions. Like seriously? Items like Hextech sweeper and the vision potion defeat the purpose of shaco, teemo, and talon players of the game mode. The game gives shaco its recommended items because it assumes the player would go the Mage route, specifically because of how high shaco's ap scalings are. So what's the point of him going ap when a potion for 250 cancels out his entire being? Or teemo's passive, or one of talon's only escapes? I can understand team comps full of cc against team comps full of squishy full aps with no tanks but a player shouldn't have a bad time because a single item was made to be used against them. And even twitch and Evelyn are under effect of this.
Most would argue "hey, would that mean removing mercurials because it would effect zed games in ARAM and ziliean game play?" Not at all. In fact it's unlikely for a WHOLE TEAM to build black sash as unlikely for the whole team to build thornmail. Unlike thornmail, the vision pot turns a single champion into a lighthouse that ALLOWS OTHER PLAYERS TO SEE Invisible champs/trap. Thornmail doesn't give every player a reflecting aura, and black sash doesn't act like a Crucible for every teammate at once, it makes it exclusive for a single player.
The same reason why the Hextech sweeper and vision potion isn't on summoners rift should apply to ARAM
TLDR: ITEMS MADE TO SPECIFICALLY COUNTER AGAINST A CHAMPION'S ABILITIES SHOULDNT BE ALLOWED IN A GAME MODE REVOLVED AROUND RANDOM PICKS.
