I've found that the League of Legends community is a lot more friendly towards new players than Heroes of Newerth.  Most of the people in HoN remind of those 12 year old Halo players....

Toxic,  
Thanks for the impressions. Since both LoL and HoN are only multiplayer games, the player community is very important. Beta testers are usually the hard core fans so maybe HoN will be better to play after launch (?). Otherwise, I'm sure some casual DotA fans might stay away. If I can only buy one of the two, I am leaning towards LoL myself. 

I tend not to judge a game based on how hurt my feelings are by the community.

So I am currently in both LoL and Hon closed beta and I decided to write my thoughts on these similar games.
As most of you know They both borrow heavily from the Wc3 mod Dota , some say they are a straight up clone . 
 
I started by getting into Hon beta unfortunately... it is not a noob friendly game. I joined a newbie server and was "raped" by the players, In later matches i asked for help 
but the players either did not answer or said that i should F of and learn to play. Here is a quote from one of my matches " What the Hell are you doing Toxic..." 
" why did you pick theses items" " you cant play this hero you suck" " that's it give me control of your character"     so I left broken. it is not the best first impression
Don't get me wrong the game is great and looks fantastic but the community ruins it and i am not the only one this has happened to. But how was i to know what to do there war no in-game tutorial no way for me to know what each hero did before i entered the game and no way for me to know what items were best for my hero 
And worst of all the game keeps track of your Kills and deaths which every player on the server can look at. 
So i recommended Heroes of Newerth for skilled Dota players only.
 
I just resently got into league of legends and here is my impression 
Ever since my first game the comunity has been nice and helpfull and you can study all the heroes in the game lobby before you enter the game and when you are ingame the store recomends what you should buy for you hero. there is also a nice leveling system were you can insert mastery points in a talent tree 
Your kills and deaths are not tracked and there is a nice rune system to make you hero even more powerfull. It has a more cartoony look than Hon but that doesent rly matter. It is going to be free but you can pay for a digital copy to unlock some stuff.
This is a noob frendly game and i highly recomend it for anyone intrested in Dota  
 
remember this is all coming from a guy who had never played Dota before
