Item cooldown reduction in Aram and heal potion troll

I enjoy playing Aram and I played lots of them. I love Riot reduced the summoner spell cooldown in Aram and it is now definitely more action going on. If summoner spell cd can be reduced, why not reduce cd on items, for example, Zhongya's. Sometimes, the cd of an item is even more than the cd of flash such as Mikeal's. Because of its long cd, people do not want to buy them, thus less interaction is happening. It is not fun to have Zhongya's unavailable for a team fight and not even up after death. Please have some way to reduce the cd of items. Also, the health potion that everyone can get on the map should not be consumable for champions have full health. I often ran into players trolling with potions when they are full health. Please think of a way to reduce the opportunity for players to troll with potions because they are important to the game. Some may argue that champions at full health get potion because they want to zone the enemy out or not let them to get it. I think it will have more interesting actions to only have non full health champion get potion because they have to put themselves in risk and really think if it is worth it. That's about my two thoughts on Aram. Feel free to bring more ideas in the comment, and hopefully Riot can take some of the suggestions.
