Since people love to harp on how wars say war mitigation is 'weak' read the nuanced version that is always ignored.
Wars biggest gaping problem centers around mitigation. Pld drk have frequent on demand cds, wars is stronger but stance locked, but has an extra CD and a low timer immunity to make up for it. It's an awkward compromise where HG and 1 extra CD is used as a crutch for for no on demand action. Which puts war in a very strong (defensively) position in tank stance, but in an awkward spot out of tank stance that uses HG as a crutch to use cds on fluff and layer them for busters.
As long as on demand mitigation (IB) is stance locked and pld/drks isnt, war will have the seesaw problem of to strong in stance and to ok, but awkward out of stance (necessitating holmgang and extra CD as a crutch). Or the alternative, remove those things and have war balanced in stance but weak in deliverance.
I would really like to see IB tone down, unlocked and HG reworked because it is an awkward duct taped together ability. In 2.x it just dragged monster to you and rooted you both. That's it. It was stylish but impractical and awkward. Then in 2.1 war got an immunity and that was the slot that got it. It was never designed for this and is just weird now. But necessary until they free up on demand stance locks.
The problem with war isnt that its mitigation is to strong or to weak. Its that it is binary based on stance and that will never balance well. The same reason weapon type debuffs need to go. You cant balance a job that exists in two states. Lets say you want brd to do 10k dps. Do you make it do 9k and assume a drg ie there? Well now its balanced with drg and UP without. Do you make it do 10k without drg and 11k with? Well now its OP with drg and balanced otherwise. You cant balance a job that lives in 2 states. You cant balance war defense if it has 2 different sets of mitigation based on stance and pld/drk have a single state. That is why war defense is problematic. Not because of HG. Not because of more CDs. Because it has 2 different sets of CDs simultaneously and therefore will never be balanced with drk/pld.
Also:delete weapon type debuffs plz. It's the same binary bs as described with brd just less prominent because the others are self applied (mnk)or have multiple sources (slashing). They are dumb. Delete.
