Guild Wars 2

yes and no..hammer it’s slow and telegraphed,gs gives you nice mobility and damage, but you can’t rely on any blocks from shield or mace.
actually i find better choices with m/sh rifle..skill number 7 at your choice.
give a look or try it..

Grenth himself can’t compete with a reaper in pvp

Hammer is very much defensive (by cc to make them un-attackable) &supportive (by making enemy CCed to let your teammate stomp) weapon than offensive.. You will feel as much as you play it. It cannot even burst huge dps that much fast like axe. So combining hammer into zerker set is not really good idea. (thus it’s not really a good idea) And like above people says, it is very telegraphed.

recommended weapon set for hammer therefore is, from my perspective
1. Hammer/mace-shield
2. Hambow probably? Outdated tho

Actually you could do extra dps while they are in stun, but after HoT expansion, many people now have almost perma stability such as reaper and berserker and etcm thus hammer or mace that has stun ability has become not really useful than before.
