HoN's death was something awfully predictable, since the game was just a DotA clone with some minor twists here and there. It was pretty obvious that the REAL DotA would be that game's natural predator and it totally WAS. LoL at least managed to find it's own audience, but HoN was a shameless cash-in. Still, I don't regret paying for a small "DotA fix" untill the real thing came along.
By the way, do you think dota2 found its audience? The number of players stopped growing, the game is staling.
- To pros, LoL is more appealing because LoL pays better.
- To noobs... in the same way that LoL is more newb-friendly than dota2, Hots is even more so.
LoL and Hots have a future, dota2 doesn't seem to have one, despite its deep mechanics. The reason is simple - a game lasts too long, the amount of heroes to chose from is discouraging, and the graphics are somewhat to be desired. Even dota1 looks more beautiful than dota2. LoL basically took dota1 graphic style and improved it over time. Hots got a variation on the wow style, which is proven to be successful. Dota2 invented their own style and it's not so good. And this shit is as important as game mechanics.
It's not like dota2 will die, but it's reached its peak. From now on, it'll only sink. Unless someone turns it around via sdk by making a more dynamic mod.
