So unimpressive that he was even deemed non-unique by the designers. I kid of course, Quickbeam is however really not my favorite hero in the game by any stretch, feeling quite clunky in numerous regards.
Firstly, he competes with his ally version which is one of the best and most commonly used cards in the game. Secondly, while he provides decent attack power, that attack power is neither permanently boostable in any serious way, nor is it ranged, a major drawback for multiplayer. Thirdly, while his ready is very cool, it is in a sphere with no real healing opportunities, forcing you into a very specific sphere-match with lore if you want to use him.
Compare that to someone like Boromir, admittedly one of the better heroes in the game, who also has amazing stats, can take attachments as he pleases, doesn't disable you to run one of the best allies in the game, starts with a lower threat cost and has a much easier time to trigger his ability.
All of these factors make Quickbeam hard to use. He does have some considerable upside, being fantastic with Peace, and Thought for instance, as well as bringing multiple actions for many stat-points from the off, however I still rarely use the hero version of one of my favorite characters in the books, usually settling for the amazing ally instead.
