I would use this place again to remind blizzard that we do not have any fast way to swap skills in combat and this is unpleasant for Hardcore players who happens to live on the edge and a second or two matters a lot for them.
I would love to be able to hotkey-swap a skill or click button hover-over swap skill while the skill menu is toggled.
For example: A player has frozen orb on action slot 1 and has the key bind “E” for that slot. It would be awesome to be able to allocate a secondary skill for that slot somewhere in extended menu, let’s say the player chooses this to be fire shield and when pressing a modifier (shift) + the key bind “E” these two skills will swap.
Also it is good idea if the swapped skill has a cooldown, some %(lets say 35%) of that cooldown to be activated before the player is able to use the skill after the swap.
Now, the other Idea I had and I already shared on the forums, which is actually my favorite way to deal with this, is just to be able to press the action slot key bind when we are hovering over a skill in the skill assignment flyout, and in that manner we assign the hovered and chosen skill to the slot of the key bind we press.
For example if the player want to change frozen orb for fire shield like in the former example, he would need to toggle the skill assignment flyout, hover over flame shield icon and press “E”, instead of dragging it to the desired slot, amidst of the heavily action infused Diablo IV massacre gameplay we are used to have.
The idea of initial cooldown activation may be taken in the same way, to limit the spamming of skill-swaps at all times, which is not the idea behind the change. It is more oriented to be utility piece in a well build character concept.
Let’s say imbue rogues might want to keep concealment and smoke grenade for some situations as swap skills, or mastery sorceress might want to keep a conjuration skill or two not as primary skills to use when the gameplay-situations is appropriate, etc…
I thing this change will be beneficial to all players, not only the hardcore part, it will open new ways to play the game and explore its system to the fullest!
