Just wait for DOTA2. Been glancing at my roommate's monitor as he was watching replays, not seeing much reason to stick with HoN. Gameplay wise it's very similar, and in pretty much every other aspect such as graphics it's superior. The interaction between sight and fog of war in particular looks very smooth, a pretty important aspect in those crucial jungle chases. What does HoN have going for it? Some different heroes and a F2P store that tries to suck the life out or your wallet. Hm, not looking so hot.
