How about Irelia's dash doesn't put her behind her target?
Irelia is obviously the typical LCS outplay type of champion, with the dash spam and all that. I only actually noticed it yesterday that she lands behind her target in addition to closing the gap. I personally think of this as almost spoonfeeding the Irelia player a sick outplay because while attacking, she completely moves out of the way of where you would be aiming your attack.
Not only is it a spammable gapcloser, but it just gives you good positioning automatically, whether its being difficult to aim at up close or placing yourself in front of a fleeing opponent. Its like Yasuo's dash except it does damage, has better range and cant only be used one time.
Also it heals her for some reason which reminds me of a certain other champion thats often mentioned as well..
