SCoB/FCoB tank busters were every 60s-ish, which gave PLD an almost optimal CD rotation (optimal would be every 90s). We don't really know what's coming in Alexander, but I imagine it'll be more of the same, and even if it's not PLD has Sheltron for a -20~30% damage reduction every 30s. We might also get a lot of forced tank swaps, like savage 9 or regular 12, so mitigation uptime would become a non-issue. Both tanks are fine for MTing, but most groups will default to PLD simply because Hallowed exists and they have a shield. Really just depends on what we're going to be up against, more fights like Ravana would favor WAR, but more fights like T13 would favor PLD. *shrug*
