Moving from HoN to DotA2 due to pressure from friends and some of the things really friggin nag at me with this game (well to be fair I havent played HoN in a long while either with me playing more on consoles this past year):
The hero selection screen is horrible compared to HoN or even og DotA with small icons where you can pick real fast if need be. In SD you cannot see what picks your allies have, you cannot see the names of the heroes your allies have under their portrait... Also enemies see your picks in SD :/
Game feels to be quite buggy for a final release of such competetive game. Sometimes the cursor bugs so that the item icon is glued to it and you cannot open or fastbuy recipes. Sometimes stuff just don't plain work like Meepo clone not getting the boots before you die, scepter not working with Banes ult thru the whole game...
No concede option. Drives me absolutely nuts on some games. The game also feels slightly less responsive for whatever reason.
This is entirely taste issue but I liked that HoN removed the need for secret shop. Been getting used to it again tho. Same for 00 runes.
Not to say that there ain't stuff that I like too. Skin drops are fun and lil more customization with different parts, game seems to run better on my PC with very fast in and out when going to windows, Phantom Lancer is back and that was one of the heroes I really wanted for HoN...
Lets see how it goes.
