The bold is the one thing I agree with and that your correct about. However, very few people will ever invest in a carbon copy, of a carbon copy, of carbon copy long term. Doesn't matter what color they are it's not going to happen long term. The very fact that DC has managed to achieve a modicum of success with two copies of essentially the same character/character type is impressive in of itself. To push further is pressing their luck and flat out greedy.
The fact that they tried to pawn off the Black version of a VERY POPULAR character as a "Gotcha" with a little "F-You" on the side is past the point of being despicable and shameful. Giving him a new set of powers that works with the Flash family will give the character ACTUAL legs to move forward into his own character. Right now as it stands the very knowledge of how the character came in to being will do nothing but stiffen him for YEARS to come.
Why? Because he will always be the character created to shut up BUYERS and force cooperation or be faced being labeled with VERY derogatory language. While at the same time ONCE AGAIN using the BLACK COMMUNITY as unimportant pawns to further their personal goals.
DC is about to go through another reboot anyway with this 5G non-sense they might as well FIX the mess they made with Wallace by actually making him his own character.
