What about the other hidden powers? I know those one are the main ones, but there are others. I doesn't make sense to be able to only pick 3 (4 if you include the yellow shard as electric)
Its not a bad idea, its something that could possibly work but you'd need to find something for the other hidden powers.
Implying the update will be soon.
Back on topic : This is a good great idea, but I personally think that if they implement it, that it wouldn't be next patch, even though its a great idea, I don't think it would be all that high on the to do list.
Or maybe the staff weren't doing enough, and this is all part of the plan to get them to do more. No more off topic = even more useless random threads popping up that they'll need to close.
