Guardians... Reckless stance - grants crit bonus instead of potency. Sets block chance to 0. Taunting Assault - faster casting. Battle Tactics - 3% damage reduction group-wide. This sets guards apart from other tanks as the low offense, high defense tank. Sentinel - 48% chance to proc 87% damage reduction on target at grandmaster. Dragoon's Reflexes - Remove "dispelled when CA used" Plant - 1 threat position if epic. Executioner's Wrath - increases crit bonus instead of crit chance. Executioner's Fury - When you fall below 50% hp... increase 5 flurry, and taunt effect and damage of all CAs by 15%, for 8 seconds (long enough duration for 2 auto attacks and 6-8 CAs at most). Arena Endurance - Previous 2% heal suggestion seems fine. Battle Hardening - Needs to soak more damage at 95.
