If you have already him at lvl 80 or more, don't sell him. Keep him and use him for the low battles in Versus events or simulator or whatever else to make combo hits and defense.

They may get around to him eventually. I don't know if they would have redone Daken if it hadn't been for LazyDaken coming out. If they want a black AP generator in the 3* meta, LazyEye would be a decent place to put it: He's got a strong passive defense power (especially scaled up to 3*, ugh) and a very strong (if high-cost) black power.

Level 2: Unrelenting activates when any teammate makes a match.
Level 3: Generate 1 black AP whenever you match a defense tile. (No longer depletes Purple AP)
Level 4: Generate 1 black AP and deal minor damage to the enemy team.
Level 5: Generate 1 black AP and deal minor damage to the enemy team whenever a defense tile is matched by
