Unique things in custom champs

One champ concept that was recently put out was Ignis, the Flame Weaver. It's pretty creative. However, it's received criticism for not having a fancy trick like Azir or Kalista. I'm here to suggest that maybe you don't need to have a fancy trick that no one else can do to have a unique champ. I'd like to direct you to one of my champ concepts, Raven Crowe, the Rage of a Dying Universe. He doesn't do anything totally unique. He's a melee brawler, uses something sort of similar to thresh's passive, only giving ad and restoring health instead of giving armor and ap. The most unique he gets is transforming with his ult and having one of his abilities change. Yet even with that, he's a pretty cool champ with his own niche, as a fighter who sticks on a target and can leap to the other side and stun them, and have a fear, to control the tide of battle in his favor, yet he needs to work on building his attack.

What I'm saying is that a champ doesn't need a fancy gimmick that no one else has to be unique. Even in game, there's a whole region filled with champs that use ice weapons, and have slows, but they play incredibly differently. It's the same with brand and Ignis: both are fire-users, sure, but they play completely differently.

All sorts of champs have similar stuff, so unless a champ directly takes a kit from another champ, it would be cool if you guys wouldn't call them ripoffs.
