Paid? Every Character can be unlocked by just playing the game, it is unlikely they paid for the Champions. Some character do have some moves that are hard to know how to counter though. Tryndamere has his Endless rage, making him unkillable for 5 seconds. Master Yi's ult which makes him immune to slows and move faster refreshes upon killing someone, making him able to snow ball in low level games. Karthus can still attack for several seconds after dead, and has an ultimate that hits everyone for a good amount of damage. Some people like Katarina can output tons of damage and easily escape. Alistar has an ultimate that makes him take 75% reduced damage for 6 to 8 seconds.Revolutionary said:Yep. My friends convinced me to try it out, and we proceeded to get our asses whooped by three overpowered/paid characters. Uninstalled immediately after and never looked back.
I'll be giving Dota 2 a shot, though.
For the bulk of these, the solution is something most new people wouldn't immediatly realize, and it is to try and have a team with some stuns mainly. Stun Tryndamere in place when he is unkillable, he will soon be killable and likely have minimal life. Stun Katarina, ultimate stops.
Other characters can be deceptive on first look that you think "I can kill him." Two major examples would be Blizcrank and Anivia. Blizcrank gets a auto shield when he is low enough in health, and Anivia will turn into an egg when 'killed'. (Though they have a 60 second and 5 minute cool down respectfully)
I personally don't think anything is all that over powered, the biggest problem comes from normal games being blind pick. Lots of people have counters (Like the counter to Karthu's Global attack is Soraka's Global heal), but you don't know just what the other team will have outside of ranked mode.

On the subject of Hero's of Newearth, I still maintain my biggest problem with the game is the art style makes it very hard to tell what is going on. League of Legends may not look as good technically, but it does a good job communicating what is going on, with its use of colors and particle effects.
