Enhancement shamas were born to do mega uber random burst wich two-handed weapon.
These days specialization itself looks like fury-warrior doing tons of small hits collect stack as other classes do. It doesn’t feel like anything unique makes those people who love windfury procs was left from the game or change shaman to another class.
When u press on a button and see how enemies hp going down, this makes feel that your buttons doing damage and enhancement shaman wich two-handed weapon had this feeling when it was windfury proc it did feel like it was a proc and if it was critical proc it was a huge burst compared to dual-wielding whats doing tons of small hits and windfury procs that do not even feel like do any damage and u are still not able to equip a shield to be more heavily against physical damage coz u cant use abilities like a stormstrike or lava lash to do damage at the same time and gein fewer stacks of Maelstrom Weapon to heal yourself. The two-handed weapon was just cut off from shaman only for dual-wielded can use melee skills.
Another point is that u can’t use two-handed as cosmetic on dual-wield for change they look this negatively affects people who collecting transmogrification items to make charter looks awesome.
