As promised COF's Oracle Build is here for your viewing consumption. I'll start by saying what I always do in my build videos. This build is solely off of what I found to work for me. If it gives your ideas by all means take it run with it makes it your own. Secondly it's very hard to make a build where almost every trait works with another trait. It seems like every patch we get a little of that ability to make a complete build is stripped. However I have found a way to make a build 100% flowing in the way I'd like to use. It's a crit build that even with mediocre gear you can hit 43-45% crit easy. I don't go higher than that in games because you something called a useful cap.
In order to overstack something useful to you is lost a vast majority of the time. So I rather make an all-around good character then a cannon not worth anything but a rez.Build is basically 0/25/0/15/30 you can see the link here. The reason this build came about is because I made a Paladin Build Series for Guardian 3 months ago. That became really popular and like.
The thought behind it was you want the cannon and the healing. But I took that a step further and gave the cannon healing and the tank. I tried to emulate that as best as I could with this character. I think I found the cannon and the healing. Unfortunately the tank couldn't join the party but if his place flexibility and utility join in.
The air tree provides crit, speed and single target power. The water tree proves healing and health to take more hits. Arcana provides healing, Utility, Debuff, Buffs, and Elemental recharge rates. I won't bore you to death nerding you out with equations. Show and prove works a whole lot better in my opinion. So check the video out and check out the build link have fun with it. PVE wise it couldn't be more it does have WvW weakness if with no toughness. However you don't really need it if you play well.
