Kayn to TFT ?

Well, I know it's too fast to write new things to add when they still need to polish the game to get out of the beta. But anyway I think it is necessary to share these ideas with you, to know what you think ...

First, well, it's my favorite champion since he came to the scene: Kayn , why not add Kayn as a shapeshifter and a new kind of class something like Yasuo whose origin is unique. Here comes the interesting this "new class" that is "unique" allows Kayn once he completes his mana on human form he will get transformed by his origin of shapeshifters, but his new form will depend on whether in the field the player has more units brawlers or more units assassins (if the amount is the same the new form will be random), Ok then the new form of Kayn being Brawler it's the Darkin Form that provides it with more life, greater resistances and a definitive new one which will allow you to use your Blade's Reach ( his W currently in League of Legends) with this ability he will heal a part of the damage inflicted and will be able to knock-up in 3 -5 squares in front of him to all the enemy champions who are in his step. Ok the other way would be Shadow Assassin which will give him more damage, more attack speed and more magic damage, in the same way that his counterpart will also use Blade's Reach (W) but this will have less range, I do not know 2 - 3 squares. This ability will obviously be an assassin so he has to do a reasonable amount of damage to his class.

Well that was the idea of ​​Kayn joining the game possibly as a Legendary unit (Tier 5). I already know that a unit is currently a passive like shapeshifter, but it is not found any unit in tier 5 with liabilities of Brawler or Assassin ..

(Sorry my bad English :( i try my best)
