A War's cross class skills usually takes provoke (you need this at high level), convalescence (stacks beautifully with Thrill of Battle), Internal release from Monk. The other two are more up to whatever. I haven't found feather foot to be very good but at least it's there. You might take flash. Second Wind can do things. Mantra doesn't amount to a whole lot.

On stats on War: You won't get consistent answers. Some think strength is an abomination and you should be pure vit. I think that's silly. Vit can be helpful if your gear isn't up to content. But if you're not getting one-shot even more HP is just wasted. At ~i100 I'm 30 strength and using a couple strength accs in everything and holding up just fine.
