This is why RoE needs a slight rework. Either by refeshing GL when activated and again when hit - or refreshed GL timer each time we're hit - or when we're hit the remaining cooldown on the damage buff is added to the GL timer (above 16 seconds max) and the damage reduction buff is lost. We don't need a further 10% damage reduction AFTER being hit because a) we've already been hit... and b) all things in this game are scaled for each class and therefore the extra 10% damage reduction isn't mandatory in any fight for our survival because classes without access to abilities akin to RoE/Earth's Reply will survive with their kit.
