Also of course playstyles are differs from person to person but
i think using armor talismans in talisman slot is heresy because you should never be tanking enemy attacks long enough for you to need high armor value and even if you do high parry(supported by righteous steel) or repel blasphemy should be your exit way out. If you want a tanky brawler
definitly WH is not the right one due to LIGHT armor. By sacrificing str you loose your biggest weapon aka burst.(if you find yourself in the positions where you have to tank you are doing something wrong)
You use 7-8 slots of talismans total ( 9 with if you run skaven ring )and considering you have 2700 armor means you used all of them with armor means you lost
22x7=154 str. 154 STR is not only 154 meele power but also parry strikethrou plus the higher str you got the less chance enemy will be defending your attack.(calculated via your str and targets weapon skill.)
In PvP
Burst kills you and if you wanna survive that you need crit rate reduction aka futile strikes least 2 points or full dominator if you really wanna go defensive ( instead of armor stacking you can try this set itself gives % 8 anti crit bonus ,but not sure how wise to loose so many crit from armor gear)(also consider anticrit works against both physical and magic)
That is it from me

Have fun everyone.
