Riot, how aren't you seeing the problem with these interactions
They completely fuck up the game. Having both of these people on one team gives that team a massive advantage in gameplay. Guess what's going to happen to duoqueue ranked? I'm going to see these champs in every goddamn game because every duo is going to spam them. So, yes, they'll get banned,but what's the point of even making a champ if you already know it will be banned in about 90% of all games. Also, what are the odds of getting both champs on the same team in the first place? Ya know, the above issue may not even happen because if a player sees the enemy pick one of these, they'll probably just counterpick the other one. look, nice thought on the design, but there is no concievable way this will work. And let's not get into the interactions. The recall especially; it's basically a free teleport if you have fingers to type to your teammate "back right here". Dash-heal is broken. Etc, etc. For comparison, this is like giving talon and zed +20% AD when they're on the same team. But NOOO that would be too OP so let's hide it behind a bunch of "interactions".
We all know these champs with their flashy animations and "cute" play style are just for your pro play, to get more people watching and spending. I would like to see one champ that lasts more than a week without being permabanned and gutted (literally EVERY SINGLE RECENT CHAMPION RELEASE except Jhin) or falling out of existence (EVERY rework (yorick, ryze, galio etc).
