Logically speaking, the game needs to move forward. Creating new characters with the same stats doesn't progress the game.

With that said, you'd be wise to save your gems and summon tickets until and event with a high probabilty of a newer unit, as those units will most likely have better stats. Do some research and figure out which characters have what you need for your team, and compare the final stats to see which one will be better overall.

It's not an imbalance. It's growth.
