Hello...ok my idea is that someone from SK team make a video for every sword and gun how they effects and damage looks like in 5* and lvl 10 so we know for what we are going to upgrade...in youtube i see just some of the swords not all of them but i would like to see all the damage and effects and so on,and i think its not just me but many of us...thanks :)
there is a wiki for this- its not the same as a video but it gives you an idea... you can also post questions regarding an item on The Arsenal forum section
