I agree shielder is propably best to start with. Try to improve your footwork while with shield, manual blocking will be much easier once you learn to position yourself properly. But sooner or later it's better to practice manual blocking or you'll be stuck with shield forever. If you decide to stay with 2h, I'd recommend greatswords. Those are very good for sneaking in stabs past friends if you stay near teammates, and with the range benefit you're less likely to get spammed to death.
