1 play a game or 2 againist ai in single player to get the feel for the characters
2 try to avoid  chasing the enermy if ur mostly melee then  get ur creep to tank the tower for a few secs and hit him a few then retreat and wait for more creeps
3 keep a eye on ur allies they may need help/ they may be coming to help u
4 focus at all times dont think this is easy ill just do this  it usually ends up in death off ur dude and them getting money and u looking like a moron
5 dont think ur better then the other people playing  because u will get to cocky and get owned
6 if u anit sure about what to do folo one of ur teammates and help them 
7 read the items in the store in battle  read them all see witch u like  and remember the price and  what they do also read the artifact store
8 buy upgrades  like dmg upgrades  or speed or armor  or citidel ones but buy some at start and keep buy as game progresses
9 dont quit a battle even if it is lagging if it is lagging then the people who usually play will be playing more slugish so for u it will give u a extra mila sec or 2 to think
10 dont chase enermy demigods  best case scenario u kill them and die ur self  witch means u get a delay return to the battle field less gold less exp less warscore (AVOID DIEING DIEING BAD)
11 at the begining of the battle look at your skill tree read the skills see witch one u like then ask ur team mates if it is a good one to start with because picing the wrong skill at start/no skill tends to end badly
12 if u find the match to hard dont quit tough it out  and it will start to get better and think  how u can help ur team
13 i dont like the number 13 so im skiping a thing here
14 look at ur team mates and think which dude would work well with them
15 like the demigod u go with otherwise ur going to be bored shitless and hate him and quit
16 read the origins on the demigods there  very cool and tell u about him
16 read the strengths and weaknesses of the demigod and the play style this may help u choose one but the play style is just one of a usualy 3 per demigod
17 have fun and enjoy playing
18 dont be a asshole and think your the best in your team it anit true there is no i in team (yes i know there is a me in team but all people who think me are assholes)
19 if u win with one  dude and u think he is good ask him for his contacted details like email  skype name shit like that so u can play together again
20  hmm im runing out of think i think might help  noobs hmm  ahh PLAY NICE WITH OTHER PEOPLE OR THEY WONT WANT U IN THERE GAME AGAIN
