I don't see how they could have done otherwise.
DotA's playerbase is well known for very hostile kneejerk reactions toward any change no matter how large or small.
The costumer is always right, heh?
There was plenty to be done. DotA 1 just stuffed in more and more heroes without balancing them properly or giving them all mechanics and abilities that require skill to use. I'll leave this to the sticky thread, however.
(...) Many Dota players look at it as casual due to the fact that it has no denies and it's less punishing. In my own opinion, that reduced the game's intensity (...)
I agree. The lack of creep denial was a letdown for me.
I played Dota for 5 years, LoL for 2 years and really got bored due to the long games, the laning phase (last hitting may be skill and all, but it's boring for me) and the community. I really hated show offs that sucked and blamed everything on the team. I also hated the idea of banlists in the original dota even though I never got banned, thanks god that was changed in DotA 2 to a less biased system.
I can fully attest for DotA 2 community being pretty terrible. Also, maybe it's just the times changing, but even though I remember DotA 1 players being flammer brats, it ended up being fun because of how ridiculous they were. StarCraft II and DotA 2 players though... it's horribly frightening how they keep attempting to push their broken logic into you and how (especially in DotA 2) they're totally beyond help.
As for LoL, I played a few games against bots and then 1 or 2 real matches. I met an occasional flamer, but, perhaps due to never going beyond some starter bracket, I felt the community was much more friendly. For instance, just the first time I played Tarik, I had no idea what I was doing or if I was even purchasing the correct gear, but still I received a complement and one or two of those "commends" at the end of the game. I remember getting quite a few during the time I was there. In DotA 2, after hundreds of games, I have around 50 commends or so.
The lack of banlists is okay, but DotA 2 really needs a surrender option. Especially to stop people from feasting on the pool.
I'll talk from an artist's point of view
one thing that really shocks me about dota 2 is that it's a bit harder to distinguish or highlight heros. it's a bit confusing compared to dota 1, where atleast some heros had glow or you could distinguish them easily on sight. It's more that i feel the art is not contrasting correctly heros from theme. (...)
Agreed. =P The first time I played DotA 2 was a huge confusion. I remember letting an enemy Sand King pass by me because I had no idea he was an enemy xD.
