For whatever it's worth, when play testing my fan-made Big Bang Theory investigators*, I found that Arcane Mastery + Prowess was a really good and solid combo for Will and Kabir (Howard and Raj).However, Dave (Sheldon) with Arcane Mastery + Marksman was noticeably more powerful than the two of them. During play, I did upgrade Sheldon's signature skill by one level, but never did use that extra ability; he was just fine using it at merely level one on the very few times in the early game when he did not get a kill on his first attack on an enemy. The higher levels ended up being just fluff to make him a believable example of Sheldon. I had thought that the black hole idea was going to be really nifty!
Oh, and Hey [user=hvg3akaek], that is an excellently clever graphical display idea to use the diagonal to tally total uses of that skill, rather than just putting a - into it!
