I'm having a very hard time finding the right one. I currently don't have the Expansion, but I don't really mind getting it, I just want to pick a class I like first.

As for the playstyle I enjoy the most, its either a classic mage style of high dps aoe, or a melee style of high damage tanky builds. I don't mind rangers but from what I've read the ranger is pretty bad especially since warrior is basically better in every way when it comes to support.

That's why I tried Warrior and ele first, but was a bit disappointed. The reason for my issue is that the classes are not "typical" or what I'm used to, so when I tried Warrior, I found its abilities slow and clunky. For example the spin takes me through a target, then I have to turn around and get back to it, which I find annoying. When I tried Elementalist I found it the most to my liking, but all the switching of the attunements was once again incredibly frustrating for me. Basically Warrior felt too slow, and Elementalist felt too fast which was the main problem. I'm not used to pc gaming yet so the keyboard is uncomfortable to me, therefore anything that requires a ton of left hand clicking is bad, so no ELE or Engineer I think.

Can anyone suggest what they liked the most and why?

I want to make a main that I enjoy and go for 100% completion with, preferably a DPS character. Eventually I can buy the expansion and use the free lvl 80 on another character as an alt.

Edit: I will be playing mostly solo open world pve, but as my main I need something that can do well in fractals and raids. I don't plan to participate in any PVP
