Well my tips are..
-Dont try to command until you have played like at least a month..
-Play on newb servers if there is any with low ping to you that have players.. they are the games that have like a player level limit of 0 to 10 or something.. playing against good players isnt very fun to learn the game since although the combat is pretty simple theres a big difference in skill lol... I think I took down my sig but it I have got 144 kills - 4 deaths or something which shows that lol.
-Put stat points into strength and HP..
-like guy said.. melee > range... so dont try to use range weapons in melee range lol..
-Dont just spam left click to attack because that will make you run out of stamina then you will attack really slow..
-If you block an attack you get an attack speed buff so try to block attacks and dont get blocked cuz then you get attack speed debuff..
-When you enter a fight try to be at max charge so you can move around them and stuff.. if you have no charge then your gonna get owned if its more than just them by people trying to run behind you while your fighting one guy..

SF = Skill Factor..
Skill Factor = exp per minute..

The higher a SF a player has means that they are doing more stuff in a minute.. try not to waste time in a game cuz every second counts.. an advantage early game can win a game later.. Anyway.. the game is fun but once you pass the fun of the game then its fun to actually try winning lol..
