It was just a thought, but I was thinking that it ought to be possible to not only equip a rock pick in both hands (as you can do at the moment), but have them both effective when mining. Maybe have that so it only kicks in at say, level 10 mining and above.
Also, you can obtain a Master Crafted Rock Pick in game, but I was thinking it would be good if it was possible to craft your own picks, so you could have a q300 pick, that maybe has a better chance when mining?
