It would be nice to be able to bind multiple skills to a single key, particularly where you are using a weapon attack replacer and a skill with a few seconds cool down. Playing a pure shaman with Savagry and primal strike, the rhythm i naturally fall into is Weapon Attack, WA, WA, Primal Strike as soon as the cool down is up. Because the mana cost is so low on Primal Strike the cost is returned from Regen in the time or before the cool down is up, and the second it takes to cast does not interrupt the Savagery counter, so there is no reason not to spam it every 3 seconds.
In this respect Primal Strike is alot like a timed proc effect on Savagery when used together. I get why is it separated into two abilities, since a dual class may not want or need to take both, but it would be awesome if there was an option to default all default attacks to a weapon attack replacer, so that while the long cast ability was on cool down the other ability(savagery) would take priority rather than the base weapon attack(sword icon).
It is purely a matter of control functionality. Nothing prevents this kind of usage as it is, so i can’t see how it would break anything. There are other instances where spamming an ability with a longer cool down is desirable and it would be nice for the default attack to default to a replacer rather than the default weapon attack during recharge.
