With the new skill bar feature, combos would be very easy to pull off with those hotkeys.
Instead of just simly click and slash, a more complex combo system would provide players the ability to master timing, skill combinations, patterns, and movement. This would be great for intense PVP battles and boss battles. I'm aware in the current D3 trailer, there are combos... like the narrator says but I'm not quite sure how exactly to do combos in D3. Unless "combo" just means a chain of spells 1 after the other...
No.. I'm talking about combos u get from fighter games. Where flinching stops opponents from attacking if the right combination of keys are pressed.
I have played a mmo that emphasize on a complex combo system. The game itself is somewhat similar to the Diablo gameplay...
Here's the example of a combo system from another game:
Lunia is the name of this mmo... it introduces a number of classes with distinct skills and combos. Like Diablo, it does have a storyline. It goes through "stages." It has crazy boss fights. And you can all do that with a friend in a party of four in regular stages. Raid stages can go up to 8-12 players all fighting a boss.
Gameplay wise, it has 1-10 skills on one skill bar all can be hotkey'd. Of course there are more skills... And instead of clicking your mouse, you use the number pad for movement, up to 8 directional movement. This set up makes combos possible as you can see in the video.. but no, its not as easy as it looks. It is fast pace and if you mess up, you're pretty much vulnerable. The poeple you see in that video played the game for more than a year, perfecting their skills in pvp battles. I'm not saying Diablo should exactly be like that, but Diablo can have the same concept in terms of combos. Mouse clicks can go way further than the number pad because the direction you can face is more than 8.
And also, Diablo would probably look ridiculous with those air attacks... a more ground combo would seem fitting.
