The morningstar is fast enough to block and follow-up attack on almost all but the most rediculous of 1v1 spammers. It is not ideally suited for 1v1, but most 1v1 weapons cant take out people in 1 hit the way a morningstar can. It has good range on the side strikes, and its length does not slow down your maneauver speed like some of the longer weapons. (The speed rating on weapons is relative to their length, and in a few cases not completely accurate, the longer the weapon the less ur char accelerates into action and moves after attacking)
A good dueling weapon if your 2h is the Two Handed Sword or the Longsword(I feel like the longsword falls a tad short on the reach, and it feels as if its been nerfed to be less spammy these days, I could be wrong), Don't fall prey to the spam game thou, the people who learn to spam start thinking their good at 1v1 and then when they go to fight some of the real pros they end up getting kicked, out-maneuvered(since spammers can be backpedal trapped/dub-steppd) and destroyed / other.
I recommend the Morningstar for battle, because it is one of the most damaging weapons has surprisingly good reach and it does allow you to maneuver and block well. I've seen some people put the 2h axes to good use also.
Practice quickly blocking, immediately after your swing animation ends, it allows your character to attack with another strike sooner if you time it right, and in some instances glitches up the following attack animation to display as if coming from a diff direction.
