Traditional or simplified?

I've been studying mandarin Chinese (simplified) for a while now, but I'm really interested in learning traditional Chinese.
Unfortunately has it not only been very difficult to find any (good) resources to study traditional Chinese, I also get people telling me I shouldn't be studying traditional Chinese to begin with because its not used anywhere outside of Taiwan.
I'd like to hear other people's opinion on this matter. 
Personally I still would love to learn traditional Chinese, but feel discouraged by the fact there are so little resources I can find online compared to simplified :/  -
