Fire/SR Sentinel: Build Critique/Advice appreciated!

[Curveball]

First time doing this! Eli Hex (Fire/SR Sentinel) is currently at lvl 46 and I'd love to get some advice on anything I might want to do, optimization wise. The build below is almost where he is now - the only change I made is that I upgraded his sentinel set to Superior since that's a relatively straightforward process and relatively achievable.

 

To my untrained eye it seems like this build is in pretty decent shape, though it overperforms on Melee defense and falls short of the incarnate defense cap for Range and AoE. Also, I'm not sure I really need hasten. Dropping Inferno recharge from 32s to 25s is useful and it looks cool in-game but I don't know if it's game-changing. Maybe something from the Leadership pool would be a better pick.
