He is by my favorite Hero so far, as well as the one with my highest K/D ratio. The only thing that bothers is that I only seem to utilize 2 of his 4 spells most of the time. I just think it's odd that I'm good at this low difficulty hero.
Is there any sorts of secrets that I'm missing with him?

Not at all :P
-Level extinguish at 1 unless you want to FB. Deny a melee creep as soon as it spawns. You could deny one for your mid to give him an edge.
-Use your shield as much as possible midgame/lategame. That means you should pretty much be constantly spamming it on you and your initiators.
-Don't max your extinguish before shield. You need 2 points really - maybe up to 3 if you're having a rough time, but shield > level 4 extinguish.
Everything else is pretty much common sense imo - don't ult near creeps. Try to nuke when they're closer together. etc
He's absurdly easy to play and can be a huge impact on a game (in a positive way) even if the player has little to no understanding of the game. Plus none of his skills are skillshots or require anything more than a quick guess as to where the opposing creepwave is.
