Assassins in the current meta

It's often been brought up that assassins aren't as viable in the current meta. In the past you used to seem them a lot, but they just aren't as strong as they used to be. The tank meta just isn't compatible. There are still instances when you see assassins, but they aren't what they once were.

I've thought as I'm sure others also have that a new assassin item might help in this matter. Perhaps an item that worked similarly to how Death Fire Grasp once did? Maybe it could also be built out of Or perhaps changes to the assassins themselves.

I don't know what the best answer is, but I miss how they used to be played. I've also heard that they will come back around eventually as the game continues to change, but I'd rather they stayed highly viable continuously. It's easier said than done of course. Balancing isn't easy, but I wondered if anyone else had any thoughts on what could help bring assassins back since I hadn't really seen much other than people saying they also wanted to see more of them.
