I agree, I would love to see or even work on pure RL approaches in NLP. I would also like to see HMMs explored more, which I think also make a lot of sense for NLP, if you think of the problem as sequences of hidden states represented by semantic frames or other hand crafted language features producing phrases and sentences.
