Man, why don't you see that your 20% Damage reduction is effectively 25% extra HP AND 25% extra healing. Here's a simple example anyone can understand: Say PLD has 7k HP, WAR will have 8.75k HP. Something that does 6k damage to WAR will do 4.8k to PLD. That means PLD is now at 2.2k HP or 31.42% HP while WAR is at 2.75k HP or also (surprise!) 31.42% HP. So in essence, a WAR not popping CD with Storm's Path and just Defiance is THE SAME as a PLD not popping CD with Storm's Path and Shield Oath. Why can't you see that and keep blabbering about 25% extra HP???? I don't get it. PLD doesn't have access to HP recovery skills because they are the tank that mitigate BEFORE the damage is dealt. Sure WAR can do it now too but not to the extent that PLD can. Somewhere on the forum if you dig up, you'll find that overtime PLD's CD is still slightly better than WAR. PLD is just as capable to tank turn 5 as WAR. Many people have done so unless you're spewing this because your OT is also a PLD then well, it's your setup that is the problem.
Inner Beast cannot be kept up perpetually (never ending). It lasts only 6 seconds and takes 5 Wrath stacks to use. In the best case scenarios, it'll still be down a couple seconds. Storm's Path can be kept up 100% but again, a WAR off-tank can keep it up just as good AND Storm's Eye. If you're refusing to use WAR+PLD, well it's your problem since that is supposed to be better than WAR+WAR and PLD+PLD.
Don't tell me about the long casting animation of Hallowed Ground like Holmgang doesn't have it. I play both too and the animation last equally as long. If you can time Holmgang, you can time Hallowed Ground and come out very far ahead since you're taking no damage compared to be left at 1 HP. Sure Bulwark increase block rate and not guaranteed mitigation but it's just like Featherfoot, slightly better in fact considering Featherfoot for WAR only increase dodge by 15% compared to Bulwark increasing block by 60%.
