That's why I take improved exhaust, plus her ultimate gives considerably movement speed and attack speed that makes her a competent melee fighter (Especially with Lich's Bane). Rylai's crystal scepter is great for those situations since it slows and gives health. It is true you have to work harder than Shaco or Twitch to be effective, but if you do it right she's one hell of a force to be reckoned with. You HAVE to play smarter with her than any other champion.
Shaco has a blink mechanic attached to his stealth that lets him close distance safely even against an opponent with Oracle's. Twitch is a ranged hero, so he'll almost be in range by the time Oracle's picks him up. Both of these heroes can contribute during teamfights without their stealth mechanic because they both have other defenses (clones and range). Evelynn doesn't have a single ranged OR defensive ability once her stealth is rendered useless.
Also, I can safely say as an Anivia player that the amount of payoff for playing Evelynn smart isn't nearly as high as it is on a lot of other heroes. A good Tryndamere or Anivia can annihilate entire teams if played well enough, but they're so difficult to use (especially Tryndamere) that you hardly ever see it.
You might not have encountered all of the things that make Evelynn bad yet, but I assure you that she is not underrated.
