Well, I don't see how your log shows there's no problem with warrior. You are doing significantly less damage than your paladin co-tank (more than 150% of your dps), and taking more damage (despite significantly less self-healing) than your paladin co-tank in what's supposed to be a physical damage heavy fight warrior is supposed to excel in.
Your gears are not subpar either, it's 666 vs your co-tank's 676, it's not supposed to be this big of a difference.
Well, just look at any of the logs:

The warrior tank is almost always at significantly lower dps than the co-tank, takes more damage, and have less self-heal+absorb than the co-tank. This definitely shows a problem. Before anything could be done about it, we must first at least acknowledge that there is an issue with prot warrior right now.
