I haven't done much PC gaming in the last few years but I used to play a good amount of WC3 back in the day.  I tried DOTA but found the large amount of elitist assholes and the huge learning curve to be a bit of a turn off.
 
I got into this beta and I'm enjoying it so far.  Seems more refined then DOTA and the fact that it's a commercial game is probably helping that impression.  Is anyone else playing?  I'd be down for a few games sometime.

League of Legends has been really cool, I had never been interested in something like DoTA before but I really like it so far.

I am enjoying it so far, if anyone wants to play my username is Breadfan

i envy those who can keep up with such complicated games

Never played DOTA but i'm in both the LoL and HoN beta. While LoL certainly has a lot more potential with the skilltree and runes, imo HoN is a much better game. LoL feels more like an Alpha version then a beta. The interface is a pain in the ass to use, lots of unimplemented features.
 
HoN on the other hand is already a ton of fun to play and once you get over the insane learning curve its a lot more rewarding to play. If you manage to ignore all the standard elitist asshole name calling etc the community isnt too bad either. those are really the only downsides to it. HoN is "finished", LoL deff isnt.

Something i post in another post.

Personally I chose LoL over HoN (I'm in both beta with more than 2 account at both.) 
At first I tried both game for one week (played around 100-150 games each).  This is what I feel: 
1.) HoN community is a bit #&%$*. Why? In mine first game I got a score of 3-4-2 (beucase of mine sucky Vid card it lag every sec, they should change defult to all nomal and low) choosing Valk (PotM in DotA). Not bad for a first game (if you count that I need to click the minimap to scroll the game because the window of window mode is too large.), but mine teammate keep blaming me just because I missed ONE arrow and dying 4 times. 
2.) The AoE spell visual in HoN need some change, it is hard to see where you are. (fixed, they change some of them.) 
3.) The health bar  in HoN need some serious visual changes. It is VERY hard to find which one is enemy and which is teammate. (note: there is a VERY thin line around the health bar, ones with red color is enemy, ones with green is freindly.) 
4.) Both have leaver protection system, anti- map hack (I assume LoL have it since you can disable Peer to Peer trans, and it is server-client) 
5.) LoL is free, while HoN need to pay a one time fee. (both approved by offcial.) 
6.) Before the game starts LoL is in a window mode. So you can do other thing while waiting. HoN need to press Window button to come out (which is annoying).
7.) HoN rating system sucks. (staff said there will be a new one though.) 
8.) HoN have a better graphic style. 
9.) LoL have better balance, not just heros but things like back door, buff (runes in DotA). (They got one guy that balanced Wc3.) 
10.) LoL is more fun in early game 
11.) HoN can deny creeps, but lol can't (but it force player to be more active in early game. This is the reason for #10) 
12.) LoL have BUSHES, where you can hide without letting enemy seeing you. 
13.) LoL have free unlimit TP without needing a space in inventory. 
14.) LoL have MUCH smaller map. (more chance ganking.)
15.) LoL config option menu sucks. (99% it is a place holder. It is a black page with option box in it.) 
16.) HoN support in-game chat by defult (no config needed.). 
17.) A very annoy per-purchasing Ad in the HoN game menu (where you log in). 
18.) LoL have more guide written even thought HoN have 5 times more beta keys given out. (I didn't count the very poor written one) 
19.) HoN doesn't have working rating-game match (they will have it of cause). So we need to find player ourself. 
20.) You can re-skin hero in LoL on your own. If you know how to. ( I dunno about HoN) 
21.) HoN hotkey is ten time more easy to config then LoL (most people don't even know how to config hotkey in LoL).  I guess it is because LoL menu is still place-holders. 
22.) HoN have Pudge.  LoL don't. (staff say they might add one if the communtiy really wants one)
23.) LoL make more sense lore-wise.  
24.) Summoner system (in LoL) is a good idea. So poeple won't leave games and create a new account then leave.
