blizz intends to revamp all charakter skills and/or talents. doesn´t seem to far-fetched for shaman to get 2h back as a viable ( at least for pvp ) pvp choice.
shaman were able to literally one-shot people. now it´s only possible with bad equipped chars without any resil/hp and a little luck BUT there are obviously ways to fix this
1.) implement changes for garanteed wf-procs in case something specific happens
-you have a xx% chance upon evading/hitting/critting/parrying/getting parried/getting evaded etc for the next stormstrike in 10 seconds to have a 100% chance to proc windfury, ignoring the 3 second cooldown-rule
2.) increase the chance for wf to proc AND crit, BUT reduce the dmg accordingly
3.) make lava-lash usable for 2h
weapon-itemisation issue with instance drops:
dk/ret/warrior -> 2h str-axes/swords/maces
feral/hunter/enh -> agi-staves/polearms
i dont see a problem here, just make sure strenght goes to the mentioned weapons and same with agility.
you might as well remove polearms/staves from plate-wearers in the process
FAZIT: yes, this is a very old thing. many simply ignore it because blizz said 2h is dead. i myself would love to see 2h coming back, and if it were with staves/polearms only ( especially latter ones i think are cool, but we would also be the only class to actually hit foes in combat with a stave, kinda like a monk ^^ )
