Hey all,
Well for my current life I play a Palie.
I started with a great sword which I used for heroic leveling. At level 18 I swapped to a long sword+shield for boss fights (I had a divine vengeance from previous life). And around level 24 I could have swapped to a bastard and shield but I didn't had any decent one

. Eventually I got one after I reached 30 (RL morning Lord)
Important: I swapped my power attack feat for bastard proficiency when I reached level 29. This swap could have been made anytime needed.
The feats.
I gave priority to THF feats all the way up to perfect THF. I also gradually but slowly got the shield feats. At epics+ I also got aerie, precise strike, scion of arborea, law embodiment. Maybe imp. stunning would have been nice but having only 5 lives and mediocre equipment I felt it won't work.
I want to point out that this build should work for anyone that has 3 lives+ and/or some stat tomes. It is a strength build, you will need to reach 13dex, 14wis (could be items) and ideally high con/cha as both you will need.
You are not a full tank but you are a reliable first liner. You are slow

but that wasn't an issue for me as long the others are not trigger happy.
I comfortably cleared heroic on r3 even solo on level. And after I swapped a bit my equipment at level 23 I also could do epic on r3.
I now started legendary quests on r5 and I feel it is comfortable. Maybe not trivial but I can run it.
This is the fifth life the previous are: wizard, rogue, druid, Artie. So not a huge contribution from there other than the stats. I also have 5 epic reincarnations which I think their active abilities do more than I'm realizing

.
I also want to point out that I didn't plan the build. I just said great sword until 18 then divine vengeance (just because I got the sword and it looks awesome) and after we see but I do think the natural evolution was the bastard and if I had plan it at level 23/24 I would have done the swap and not at 30.
I balanced my enchantments among kotc and defender. My idea was to last enough to deliver my damage. I used heavy armor and now medium as I crafted a dodge belt. You need the PRR and MRR to survive. You need 20% concealment, 10% incorporeal at least. And I got 25% dodge. AC helps a bit but I don't have very good items so I would say you get an other 10% defense (monsters miss on 3) but some might make it to be a bit better.
So if you do the math you end up with around 51% defense for mobs and around 30% for bosses before PRR and MRR.
Tanky enough to be a front liner.
Have fun.
Ps: when I have time I will try to bring the build details here.
