I can understand your critisism, but the fact that her Q is both defensive and offensive forces to choose how to use it, much like Zed's W, as he can use it to go aggresive, or get away. And the very complicated wording on her E (I think her W is just fine) is simply there in order to fit the format of the wiki better. If needed, I can always change it back to what it was originally (I changed the wording heavily to make it fit here) In fact, I'll try to help clarify by giving you a slightly easier-to-understand version right here:

Eurya Enhances her next Q to gain bonus Range, as well as teleporting her behind her target on hit. Upon Teleporting, Eurya instantly refreshes her Q cooldown. Her next Q will be a linear skillshot that will do an additional (5/10/15/20/25 + (35% AD) Physical Damage) and consume 20% of her current HP, the health cost is refunded if she lands her second Q. If the Target is cursed, Unholy Cleanse is activated and will remove all positive buffs currently on the target for 4 5 seconds, and removes all crowd control and damage reducing debuffs affecting Eurya. Unholy Cleanse will also reduce enemy armor and magic resist by 15% (Unholy Cleanse cannot be activated on the same target for 45 seconds). Unholy Cleanse can only be activated on champions, and its cooldown is reduced by 0.5 seconds when she hits a target with her Q, (doubles against champions)
