What if.......
One issue I see with that is the hero point cost. Normal leveling, you wouldn’t be able to max it out.
They’d have to completely change their design of Elite Specs in order to allow that. They’ve designed them to specifically be post-level 80 content, as evidenced by the fact that you have to first max all your other specialization lines before you can start your Elite Spec and the cost, which goes beyond the hero points you get from leveling.
There’s also the fact that elite specs are designed to only fit into the last slot in your specialization panel, and that doesn’t unlock until level 71, so even if they did get rid of the above restriction you’d still have to almost max your character to use your elite.
