This is a Stamina Templar (Stamplar) build that I put together yesterday. This build is meant for Open World, BGs and with a few adjustments, Dueling. This screen shot shows what the potential stats can be with Continuous Attack, Blood Spawn and your Weapon Dmg glyph proc'd. Keep in mind there are plenty of adjustments that can be made to cater to your play style, but this shows that medium armor is still alive and kicking on anything other than a StamBlade.

Since I run solo or in two to three man groups I find recovery is a must and resource management is key, especially with multiple people hitting you with cost poisons these days. One thing Stamplar without bows lack is mobility. To resolve this, you can run speed potions or simply replace (Rending Slashes) with (Quick Cloak) on the Main bar. If you were to run in groups you could get away with running the Warrior Mundus or converting the two Stamina Recov jewelry glyphs to Weapon Dmg.
Hope you all have fun with it, enjoy!
