Playing an MMO with a controller

[Zfz]

Its personal preference. But I think you have way better movement control with analogue stick and buttons much easier to press then keyboard buttons.

You can move while pressing down on mouse L+R as well, which I often use. I could also select targets using the mouse while moving with my keyboard. I think essentially controller mode is very precisely optimized for the game, while keyboard-mouse mode is the usual versatility mode that can end up better or worse than the controller entirely depending on individual preferences.

Personally I find the camera control on the controller quite imprecise.

I played one on KB/mouse for awhile and could only make use of 1-6.. Cramped my hand and skills on the move were too hard. Controller is much more freeing for me.

The keyboard-mouse mode need a lot of keybinds customization. For example, my left hand covers 48 key-binds without having to move its position even 1 inch.

In the end it's all just personal preferences.
