ARAM Really Needs Updated / Patched Up
1.) Team comps are complete garbage in the majority of games. They aren't even fun matches to play, a lot of times you know before the match even starts that unless the enemies are worse than Bronze V players, you're probably going to win or lose.
2.) ARAM doesn't teach realistic item purchases and encourages feeding. Many champions are unable to compete with the range and damage of several ranged enemies striking them at once and can only engage with abilities which often times have very long cool timers. This teaches players often questionable methods and builds for playing certain champions. The mechanic of having to die before being able to purchase is completely wrong in so many ways as well.
3.) Player abuse the "random" method of the mode by limiting the number of champions they have. This defeats the whole purpose the game mode. If I'm not mistaken, ARAM is meant to test you and help you learn a wide variety of champions... not prove how good you are at all your best champions against a bunch of players forced to play champions they might not be that good at.
I really suggest following the role layout of ranked in ARAM to help better balance teams in ARAM.
1 Marksman 1 Mage / Assassin 1 Bruiser / Tank 1 Assassin 1 Support
Who gets what role and champion can still be completely random, however these games really need some type of comp layout to prevent teams like 4 supports being forced to play troll builds against legitimate team comps just to maybe be capable of competing.
I don't see the reason why players are unable to recall and purchase items like normal. The "death to purchase" should really just be removed from the game mode altogether. A better method would be to just add a small cooldown on recalling so that players at least have some wait before cashing in.
Increase the number of champions required to play ARAM. Boost ranged champion movement speed, give melee champions starting tenacity and increased armor & magic resist.
I rarely play ARAM anymore, simply because the game mode is not fun. Perhaps my suggestions are not the greatest, however they are legit reasons for myself not liking this game mode. The idea of fighting on a 5v5 one lane map with random champions in itself isn't bad, however the execution for the current mode on live is lacking big time.
I'm sure all the "ARAM mains" will hate my post and down vote it, but these are the very same players that make casuals hate ARAM to begin with. They spend their time creating "ARAM accounts" and learning broken off builds and mechanics that are far from viable on normal modes just so they can have the advantage over players who are just trying to have a good time.
