The lvl 1-25 zones most mobs are fairly standard and dont really have attacks that hit hard bar the skeletons, next zone steps up a fair amount more and you will need potions and healing food unless you are really quick at killing or dodging.
If you want weapon mastery levels get a group together and farm a suitable level elite area like deadmans cove, its great for some decent gear if you are lucky but the main thing is weapon mastery levels, getting more weapon levels helps a ton.
