how do I improve this mace/invuln build?

[Greyhame]

I just got this guy to 50+1 today, and I'm still running lvl25 common IOs.  I've been planning a no-expense-spared build for a while but the last time I played invuln was before IOs existed, so advice would be welcome.  I've attached the best I've come up with so far, and hope to make quite a few improvements.  A random brain dump of my build goals / thoughts below: 

 

• I'm keeping Combat Jumping - its essential combat mobility imo
• needs to be functional at all levels of play - I exemp for TFs a lot
• not a huge fan of damage procs; I don't hate them, but I like set bonuses more
• I tend to prioritize decent survival and endurance management first, then damage
• I've had trouble figuring out the right balance of bonuses for recharge (DP), resists and defense
• I wouldn't object to Gloom, but ran out of slots to make it useful, so I grabbed Assault instead
