In my opinion at the moment the current Action Bar implementation is really too limiting. 10 slots are way under what's needed to store someone's actions, especially in a game in which one can hybridize classes and use actions from all of them at the same time. Having to scroll between multiple bars is, as well, quite inconvenient and unconfortable.
I would suggest either implementing longer action bars by default (with 20 slots), or make the action bars extensible (from 10 to 20 slots). There's no need for the slots from 11 to 20 to have a hotkey, as they can easily remain mouse/joypad activated.
I would also implement a hotkey to switch between different bars without having to use the mouse.
Finally, I would plea for the implementation of a system to allow us to save our action bars for each class. I'd really like to have the game save, for instance, my action bar setup for my gladiator, my conjurer and so forth, and then automatically switch between them when i change class.
It would make the armory system much more streamlined and enjoyable, as now, unless one goes through the complex and long process of making a macro (and keeping it updated), changing classes is quite a pain, having to reset all the actions on the bars.
I would also do the same for crafting traits and guild marks abilities. since it's very easy to forget to reset them every time one changes class, especially when switching to a lower level class, that removes them from their slots when they are over the limit.
note to the moderators: I erroneously posted this on the general section on the forum as well, unfortunately the forum structure is a bit confusing and suggests that this is the forum for the feedback on the site/forum only, while reaing the sticky posts I realized that this is for suggestions in general on the game as well. Sorry for the mistake. Feel free to merge/move/delete the threads as necessary appropriate. Thank you.
