I'm not sure what you used as your second weapon, but for the majority of classes, you ARE intended to be weapon swapping. This means having 10 weapon abilities, and four utility skills of your own choosing, plus your heal, and your pet's ability if you are playing a class like ranger. That's about the same number of buttons you'd have available for skills in any other MMO and you'd likely have a similar rotation difficulty.
If it's not for you, it's not for you...nothing wrong with that. It's quite a bit different from other games, with the focus on self sustain with your own heals and dodging, but I just wanted to point out the bit about weapon swapping.
