People were going back and forth about this on the "What's New in Heroes of Newerth 2.0" quick look that Brad did. I chimed in a couple times, I mainly thought it was amusing how everything in HoN is basically a shameless ripoff, even the new stuff they are doing.
When HoN first came out, their main pull was "HoN is DoTA but modernized." Which basically meant they shamelessly cloned DoTA down to the letter, and didn't change much of anything except for the infrastructure surrounding it. Which succeeded in getting all the hardcore DoTA players to come to their game. However, once they realized that wasn't bringing in any new players, they basically started ripping off everything the team over at Riot are doing with LoL. This is extremely evident to anyone who pays attention, and follows both games closely...
Which makes this little tidbit I found on the LoL forums even more amusing.
"One of the reasons we're being a bit more secretive than previously about all of the cool things we're working on is because we don't want to tip our hand to our competitors who have demonstrated a clear willingness to emulate things that we are doing.
We will always be the innovators in this genre and the things that we are working on will not disappoint."
The Riot company is made up of THE people that originated DoTA. They know what's up, yet they also aren't afraid to innovate. The guys at S2 games are basically in panic mode, and trying to rip off every original idea the guys at Riot have in order to desperately bring in some business. Do yourselves a favor, go with the company/game that actually innovates, and is leading this genre. Not the copycats.
