well yes, im not a admirer for best undefeatable items or winning fights by equipment pressure. I also support that skills and tricky minds and finding tricky combos with skills mixing and kinda things be such important and decideful of a fight.
But same time i also would support that to clench our build and skills synergy we might have some kind of item-ic bonuses and maybe masterization as i mention above, it is for provide to be hard reaching by other players and not copy as they see it from me(my skillset, combos). and maybe some not-revokable things for customizing our combos and skills also would be fine.
I believe that if everything cannot be reachable that "easily"(i dont mean not reachable): skills, different type of items, crafting etc. and if they add some stronger effect to our gameplay(not such strong or less like there is nothing). There will be stronger parts of players and weaker parts between. and we live together create compositions by. There will be rpg elements and roles. maybe crafting and trade focused players etc etc...
