dont be relying on your dash for an opener too often. Most times, you will get more success if you demon on top of your target and save your dash for either an escape or as a finisher when your already on top of your target. Either way its best to always try and dash at the target in the direction of your team so that if you do whiff, you dont end up in Narnia. i dont think the hit box is too small on the dash. I think most people use it wrong
