Elise, can deal massive unexpected dmg if you use her right. she has a few combos and a few set up items. just play smart. I've seen a few great Elises recently.
Darius, sigh. Another complainer. Darius is all about your opponent being mispositioned. A good poke range champion can shut down Darius' early game. Ironically, Teemo works great. If you get up close and try to have a sustained fight with Darius and try to run away, you are going to have a bad time.
Fix Alpha strike? Hmm, that may just be a small bug that happens. I'm starting to notice a few icon bugs recently. Maybe you should report it as a bug in the correct forum instead of just complaining about it.
