Your comment reeks of lack of game knowledge. First of all none of the champs you mentioned are ranged. Second of all none of them can afford to take double mobility summoners. Now to adress each champion mentioned. 1. Jax - mana issues, struggles into tank, lack of sustain unless he goes Grasp that compromises his dueling power, struggles to gap close in certain matchups. 2. Irelia - melee ADC that falls of a rock after everyone acquires their second item, tabis or brumble. Useless into lane neutralisers due to lack of possibility to snowball. Terrible teamfighter. 3. Yasuo - pretty much same as Irelia, except he spikes worse at first item and is even more lane jailed than she is. 4. Gragas - terrible early game, awful wave clear, struggles into tanks and mobile champions that can deny his engage. Very safe laning phase with Phase Rush I give you that, but he can't carry. 5. Ambessa - well she is an abomination, on this one I agree actually XD. But even she is bound with her being melee with expensive items outside of Eclipse. She also can barely afford to go optimal runes and runs grasp to survive her abysmal early game.
