Did you even read what I was talking about? It's an example.. Now you talking about crits... OBVIOUSLY crits make a huge diffrence wtf I wasn't even talking about that..You don't hit anyone for 4k after mitigation without some damage increase buff e.g. near your warcamp, so 2k guard damage is not to be seen.
Like everything you mention about guard is wrong and not how it works.
Let's imagine for a second that you indeed deal so much damage, then...
" If I hit a sorc for 4k I should hit a sorc after guard for 2k and the 2k damage should be hitting the tank 1 to 1 unless your block or parry the guard damage. "
...is exactly how guard works.
The perceived higher damage reduction you notice has other reasons.
The damage difference between a critical hit and a non-crit is huge for sorc/be due to their high crit dmg bonus. It seems you compare a crit with a non-crit after guard. Absorb on your target further reduces the damage and removes the chance to critical hit.
Idk why but I'll try one more time: Take 4k damage right? Non crit right? Those 4k damage hit a non guarded target for shocking 4k damage (Still an example btw dont get it twisted). NOW imagine if I hit a guarded target. Those 4k NON CRIT SAME DAMAGE NOTHING ELSE would not equal into 2k damage for the tank and 2k damage for the dps. It gets mitigated and than split between the tank and dps. Do you understand that? Before guard damage is applied its gets mitigated by defensive stats! Block and parry can mitigate 100% of the damage.. Do you understand that? Guard does not just split the damage as explain in the tooltip it gets further reduced by the stats of your tank.
