Kayn's #1 problem as of now.

With the recent buff to his ult, Kayn is in a fairly good state. However, the Shadow Reaper still has one big problem - that is, his base form passive. In most of the games I've played I found it to be very easy to unlock his Shadow Assassin form, but nearly impossible to unlock his Darkin form without having to wait 4 minutes, and the reason is simple. So, long story short Kayn gains points towards his Shadow form by attacking ranged champions and he gains points towards his Darkin form by attacking melee champions, but therein lies the problem. Most of the champions you attack are going to be ranged, because mid and bot lane usually consist of ranged champions, whereas the top lane and jungle primarily consist of melee champions. This presents players with a 50/50 ratio, but that ratio get's reduced to 1/4 when you take into account Kayn's weak early game, which makes it nearly impossible to kill the enemy jungler unless they've already been weakened or if you have assistance, thus only leaving the player with top lane. Basically what I'm trying to say is that stacking Rhaast is very difficult, and usually means you'll have to wait 4 minutes in order to unlock it, which is ironic considering that that's his more popular form at the moment. Overall, I would like to see Riot either reduce this timer, or better yet get rid of it altogether, because it's detrimental to Kayn's kit. He's supposed to be able to change forms depending on what his team needs rather than the type of champs he's able to attack, because realistically you won't always be able to hit the type of champs you need. Sometimes, but not always, which creates a gap in consistency. Another thing I would like to see is the ability to automatically change forms after 20 minutes, that way Kayn won't fall too far behind in the mid game should he not be able to assist his teammates. It rarely ever comes down to that, but it can happen nonetheless.
