Kayn in ARAM feedback
Had my first game as Kayn on ARAM today and noticed a few issues with his core in terms of power generating and choosing a form.
1: Generating power takes way too long in ARAM. I did not unlock either form until both bases were pretty much opened up until the nexus turrets. ARAM is a lot faster than Summoner's Rift so he should be able to unlock the forms at a much faster pace which leads to the second problem that Kayn has on ARAM.
2: If the other team consists of 4 ranged and 1 melee but you need CC because they also have a lot of disengage (preventing your team from getting to them without losing 50+% of their health and having the enemy run all the way back to safety) then you cannot pick Darkin until FOUR minutes after you gathered enough power. With the constant poking and disengaging that might occur (not every game thank god) this does not leave much choice in picking the other form. This means that, with the speed of ARAM games, Kayn can't truly use his kit in a lot of situations until it's too late making him a detriment to his team.
3: "As Kayn you're the only champ that can fully change roles in the middle of a game. Choose wisely" <- This was stated in Kayn's Champion Spotlight but due to the long duration on being able to pick the form your team might actually need and the fact that you CAN'T change form after picking one of the 2, being forced to choose the form that does not help your team whatsoever due to the fact that the other team might have 4/1 melee or 4/1 ranged and you needing the form to deal with the issues your team is facing or having to wait several minutes means that you're essentially just dead weight.
ARAM specific suggestions: 1: Reduce the time it takes for the other form to become available as ARAM games are much faster than Summoner's Rift games. Instead of forcing a player to wait for 4 minutes (which might be crucial as some comps start becoming good "late game" whereas others are better for "early game") make the other form available after 30 seconds of maxing power.
2: Increase the power gained from damaging/killing enemies to allow the Kayn player to get to their form much faster. We can't recall in ARAM and running back to the fountain just to change form is a waste of time in a lot of situations so players would still have to wait until after they died in order to pick their form. If the player is stuck against a poke-heavy comp then they can hardly get power resulting in a longer delay on maxing out.
If suggestion number 2 is not an option then 3: allow Kayn to passively gain a set amount of power every second (or few seconds) so he can still progress towards his forms.
Remember Riot, you increased the speed of ARAM games with all those changes a while back so surely you can offer champions such as Kayn (and possibly future champions with similar kits as well) a solution that help them out in ARAM? There's a buff/debuff that decreases healing done (among other things) for example where you can implement a static power generation for Kayn. A few patches ago you even gave all melee champions a basic MR increase specifically on ARAM so we, the players, know you're capable of coming up with a solution for specific gamemode problems (brand passive in Doombots is another example).
