I have been playing league since season 4. This design seems like it takes a little from Leona/Taric. She feels extremely underwhelming. Currently she has the highest risk engage in the game without the reward. I'm under the impression that she was made slow when unmounted and given slow attacks to possibly keep her out of top lane. (Bruiser Build). Riot should not be trying to control the meta and where champions should be allowed to go. Currently if Rell engages and its a bad engage.. she has no way to escape with reduced movement speed. Leona can simply walk out and pop her shield for high resistance. Rell is basically a worse version of leona. No to mention Rell has ZERO damage. As a support player I was really looking forward to this champion but it's currently the weakest support.
