What i can't stomach is changing class to a miner or fisher and then switching back to a pugilist resets all my bars, and i have to go through all my skills and replace them again, and again, and again... that is a very simple fix, and if Square refuses to fix even that, when are they going to fix the major issues? Like Memory Leaks and whatever else pops up.
You can work around this in the following way:
Now exit out of the macro setting dialog all the way back to normal game. Now to change classes by using your macro, hit Ctrl-1 on your keyboard (assumes you put in upper left slot). It takes about 1 second per ability for it to load up your action bar, but it is easy as you just wait for it to get done.
That's not the point.
It doesn't matter that you can work around it - you shouldn't have to.
They've made the idea of changing classes whenever you want a central part of their pitch, so to make class-switching an overcomplicated hassle by requiring players to manually reassign abilities or write out a macro to do so (which must be updated every time a new useful ability is obtained, and which will eventually require multiple macros to perform due to the 10-line limit) is beyond poorly thought-out - it's the height of stupidity.
The game should remember what abilities (and possibly non-weapon gear) you have equipped on each class and automatically set them when you change classes. That it doesn't is absolutely inexcusable.
It's not like this is some minor side-issue - this is a core usability problem with a core gameplay mechanic. That they were completely unable to see the need for such a feature reflects abysmally upon their ability as game designers - if they cant get this right, why should I trust them to get anything else right?
And then consider the myriad other design decisions that give the impression that the left hand doesn't know what the right hand is doing...
I want this game to succeed. I want to believe that all the flaws that currently exist will be addressed soon; but I have absolutely no faith in their ability to do so.
