Added mods for pvm are hit area attacks as they provide a similar approach. The whirlwind ability is a highly popular special ability as it hits multiple targets when enabled thus leeching off of each target hit. Hence why the general weapon of choice is the double axe. PvM is all about your ability to hit multiple creatures with a single swing while having leeches (mana, stam, hit points) to replenish you stat bar. No, do not anticipate stacking sdi with the anticipation of making a quad hit spell weapon and one shot a player because of the spell damage. However take notice that SDI is capped for pvp and the cap is so low that any general player will achieve this markup. All bows have the ability to have the hit spells added to them via either crafting or levelling. Each has their own benefit based on special abilities. Mages are balanced across the board as far as which bows they equip. Parry kits are just an added bonus and for most players, far too expensive. Pvp uses bows because with a 1 handed deed added to it, you can equip a shield and add balance to the bow to chug potions without having to disarm either your weapon or shield.
