I actually used to enjoy playing ARAM
But holy shit, Dark Harvest and Warmogs need to go. Now.
It's not even the ARAM-only accounts. I can live with those. I can live with playing against Sona and Veigar every game, but Dark Harvest and Warmogs make the mode completely unplayable.
Either disable the keystone entirely or nerf it so that it's not a must-have on 90% of the ARAM roster. The fact that you can get 200+ stacks by 15 minutes is actually insane. Hell, you don't even have to build damage since Dark Harvest provides more than enough already. Did Riot seriously not think this through? Did they not realize Dark Harvest's damage resets after every takedown and think "hmm this may be a problem in a mode where people are dying left and right". If you're not taking Dark Harvest right now, you're deliberately putting yourself at an extreme disadvantage, and this is completely unacceptable.
Warmogs is the same, but from the defensive side. There's a reason GA doesn't exist in ARAM: it's because you're NOT SUPPOSED TO LIVE FOREVER. You're not supposed to get second chances. ARAM is supposed to be the mode that puts the "battle arena" in MOBA. A giant clusterfuck of brawling where you die and respawn again and again until someone loses. Warmogs completely negates this philosophy.
And it's ironic, considering Riot already introduced lower healing on allies simply to enforce this, yet they keep Warmogs so everyone can become Soraka. Mages build it as a 3rd item and still burst through your team with no repercussions because they can simply heal up to full by walking away for 5 seconds. And don't even try to tell me "b-b-but melee champions need Warmogs to compete against poke comps!" because they don't. Snowball was introduced for this express purpose, and it's the best thing to happen to ARAM since the mode's inception.
I know ARAM is merely an afterthought in Riot's mind, but they should still realize that it DOES have a very dedicated fan base that it would not be in their best interest to ignore.
