I am usually always open to giving people pointers when I'm online. I respond to 9/10 PMs, and will happily spar around in my guildhouse with you.

My general advice is to spar people that are a little better than you and work your way up from there. If you do nothing but spar low skilled players, then sure your record will look neat but you'll lose when anyone of substantial dexterity goes up against you.
