How Can I Improve My Earth/Fire/Ice?

Hello fellow Doms. I've been playing my Earth/Fire/Ice Dom since the intro of GR. He was my first Praetorian and quickly became my main. I love the combination of control, damage, and de-buff he carries. I've built him primarily to be perma-dom for as much content as possible, which was pretty easy thanks to HVM's. (Makes those lvl 25 LotG's cake to get.)

I play him exclusively at range, hence the lack of Incinerate or Combustion. This has led me to a secondary goal of ranged defense. I've managed to get him to 28.3% to ranged when stealth suppresses. I feel like I'm probably missing something obvious due to staring at it for too long. Does anyone see something obvious that I'm missing that could shore up my Ranged Defense a bit more? Or other obvious suggestions that I may be missing?

I feel like he plays wonderfully currently, but there's always room for improvement. Especially with i20 and the trials on the horizon. I've got a couple billion to play with, so I guess I could get into PvP IOs, but I've never really delved into them before. (Mostly due to i13pvp, but that's for another thread in another section.)

Seeing Earthquake slotted with Dark Watcher's may seem odd, but I had a few extra slots and liked the extra recharge and damage boost. It also boosts the nice -tohit in EQ.

Thanks in advance.

I'm at work right now so I can't give specific numbers. I understand going for Ranged defense, but I wonder if it might be easier to go for S/L/E/N which will cover you from the vast majority of attacks. You have the option of the armor in Ice Mastery, which you don't have right now, to give you a good chunck of the S/L and Thunderstrikes are great in those ranged attacks for the E/N. You said you've got cash to spend so Kinetic Combats might not be out of your range of possibilities.

When I get home tonight I'll pull up the build and look at it (I'm currently leveling a Earth/Fire dom that will take /Ice as well, just haven't gotten around to doing a build in Mids for it yet)

Just a small side note, and really about personal preference, so take it with a grain of salt. I think your Super Jump and, possibly, combat jumping are a little overslotted. With Hurdle for free now, you're already approaching the cap for movement speed. Throw in a jump speed IO in the first slot of hurdle and you're probably pretty close. If reaching that cap is important to you, by all means spend the slot, but I think the second one isn't really giving you anything. (Again, stuck at work so can't give you concrete numbers) As a small tweak, I'd take out one of the slots in Super Jump and add a 6th to EQ and place the Achilles' -RES Proc in there. More -Res is never a bad thing.

Only thing I can see is possibly to find a slot to add to Stalagmites and put in a set of Stupefy. You loose 3.75% recharge but gain 3.125% to ranged. Anywhere else you can add ranged def come at the cost of more recharge. (Trap of the hunter in Stone Prison for example)
Here is a link to my build but I'm not sure it will be much use for you as I went for s/l softcap.
