Just got a Key a few days ago and have been slowly getting back into it. I loved War3 DOTA and probably played it for 10000 hours back in high school. I've gotten in 4 games so far (wish I could play more but I usually play at 1 am pacific and there are no gaffers on at that time and it takes forever to find a game), lost 3 won 1. I've been randoming lately to just try and get a feel for it again. I know a lot of my suckiness has to do with my lack of practice and that ease of use will come with time but that being said, I do have a few gripes with the overall game.
The first is that there is no attack move or follow attack as there was in the War3 DOTA. For example I was playing beast master and I wanted my boar to keep attacking the lane creeps while I took down some creep in the jungle. It wouldn't do it. I had to manually select each creep I wanted it to attack or put it in the general location. But once that first wave was cleared it would stay there since Attack Move isn't possible. The other thing I wish they added in was Follow Attack where I can set my pet to follow me and it will start attacking if I attack and then stop once I stop. This was a pretty useful feature.
Second issue is with the overall pointer. Maybe I haven't gotten used to it yet but I feel like when I click on something, I can't really tell if I've selected it. I had a really hard time selected my bird as beast master. The other thing I wish happened was that the mouse would change shape with a spell or move is selected. For example, in War3 DOTA hitting "A" would change the mouse icon from a pointer to a sword with a red cross. Just makes things easier to distinguish.
Third: The shop layout. Maybe I'm just wanting nostalgia from the old DOTA but I really wish it was separated out into sections instead of tabs on one dude. Being able to access the shop from battle and not having to scroll back like before is quite nice though.
Forth: This may be just me but I feel like the entire game is zoomed-in a little more giving less total vision of the field. like the heroes seem bigger.
Fifth: While I'm loving the art style I wish it was a little brighter overall like War3 DOTA was. It made things really easy to distinguish and separate. Give the heroes colors to keep them from blending in with the landscape. Also, the goddamn trees. I almost hope they change it to all trees being exactly uniform and short. Right now, its distracting and its very difficult for me to discern paths.
Sixth: Over all HUD seems to be a bit too large and wish they would stream line it more. When I click on a hero I really don't need to see/shouldn't see which skills they've picked and stuff. And the game menu system seems clunky. The whole watching games, finding games, with all these news feeds.
Seventh and lastly, and this is probably because I haven't gotten used to it, but the overall game seems slower. Almost like its a bit laggy. I feel like spells take .25 seconds to go off. I don't think this is lag with my computer or ping because when I tell my hero to move, it does so immediately. I only really run into this problem when casting spells or attacking.
Aside from these issues, I'm still loving the game. I'm not going to go into the merits of the game because they've all been said before, ditto. I get that this IS beta and most of the issues I have will hopefully be fixed.
