He's dumb, or a troll. IMO it's a Clear example of someone who rushed to level 50 the week of the games release and has nothing better to do now than sit around in Revenant's Toll and complain about the game on the forums until he can find a full AF2/DL/Allagan Relic +1 group for WP speed runs.

CM/PRAE/WP/AK/Ifrit are the first tier of endgame content. They were designed to be completed in AF and leveling accessories. Any tank in that kind of gear is going to have under 5k HP, except warriors who might have a little over 5k with defiance.

It's ridiculous to assume, as the OP apparently has, that SE expected people to grind prae/CM for full DL before going into either WP or AK when the gear that drops in both of those instances is lower ilvl than the gear you can get with Philo tomes.

My main class is Paladin, I tanked WP/AK/Prae/CM/Ifrit/Garuda in AF and aetherial when I was starting out. It's not hard if you're capable of understanding fight mechanics.
