Before you say rebels is shit...
Rebels is definitely not like the clone wars sadily, but it does have intresting and original characters. Although it's more like a kids show, however look at clone wars in its 1st two seasons. And they are going re-canonise many thing (hammerhead frigates, sith holocrons ect).
What character would you like to see come back into canon?

Everything from the Old Republic Era honestly...as for Force Unleash, just the main story with light side endings. Side Note: They have yet to kill off Shaak Ti in the cannon. The Episode 3 with Grevious was confirmed not real. Then they rid the expanded universe, so she didn't die to Malek.
