Stealth/ invisible

stealth is one of the few things some characters have in the game of league of legends but some characters have better stealth skills or passives than others. for example i main twitch as adc i have since his first release and i do admit that his stealth skill was to op but after the rework now that it has a range that people can see me in which balanced it out a bit but it also the range in which they could see me in is a little to big and also takes longer than it use to to activate casing it to be kind of useless when being chased unless if i forcefully take flash or am helped by an ally player but i personally don't like taking flash and what if there is no ally to help me. then im just dead. The same is with evelynn shes almost like using talon except that she can stay invisible as long as she wants but the same goes for her invisible passive. The range of her passive is just crazy enormous thats its basically rendered useless the only way to counter the range on her passive is to get a lot of movement speed to where by the time the stealth goes off you might be close enough to deal damage./ Invisibility these are more annoying than anything and a little unfair to be honest. Shaco and Wukong have the most similar skills of the invisibility list because the way i seen in most games they go invisible and just poke over and over again with out really being detected as easy as the stealth. i also realized that all the Invisible champions can easily one shot other characters and have no range in which people can see them in not really giving them a fighting chance when dealing with it most of the time. i suggest just putting a range on each of them or at least make it more noticeable like Rengars ult
