help optimize a lvl 18 Warden

[Flipguarder]

Few things to know:
1. DM is giving paragon defenses free, and it doesn't count as a feat bonues.
2. DM is giving weapon/implement expertise free for every weapon/implement we are proficient with.
3. My party has 4 people. Others are Human artificer, shadar-kai Beastmaster ranger, and a deva wrathful invoker.
4. My background is a house creation that gives strength instead of cha for intimidate and gives me +1 to nature.
5. My DM is going to allow the use of intimidate as a minor action to goad enemies into attacking me.
6. We will have an average of 3-4 encounters per day (yes I know thats low.)

Looking for more efficient ways to spend my feats and better item feat combinations. Im happy with my weapon choice though.

Thanks in advance

Your first three feats are basically doing a bunch of nothing. Retrain them for Berserker's
Fury, Acolyte Power (Storm of Blades) and Armor Specialization.

Multiclassing into fighter did seem important at the time, and your combo to grab storm of blades being really powerful. Thanks for the advice Ill, run with that!
