If you want to try it a ton of content is free. It is the reason it is the mmo of choice for broke ass kids as their first mmo. Relatively low system requirements, don't need to install huge program files or use a launcher, and free to play with loads of fun to be had without spending a dime.
There isn't much to loose but time in trying it. If after a few months you find you like it enough to spend money then they have those cards you can buy to use even if you don't have a debit or credit card.
That said I have played almost a decade so I don't know how much gas changed.
