Currently the game is very boring and kinda routine. Same things happen over and over again, characters use same combos over and over again, ganks or some unstandart situations are almost never happening. Almost everything relies on movement speed. You have more - enemy has no escape unless he portals unless you interrupt portal. It comes down to having more slow and higher ms. The gameplay feels much less fun than dota, where you have terrain, hills and canyons, you have woods to roam and trees to hide behind, you have night and day that makes dramatic change in view range.
Problem lies in those factors:
1) No ultimates, long cooldown powerfull spells.
Nothing happens like Earthsaker or Sandking blinking in with ulti, Warlock dropping and infernal, Enigma casting blackhole, Rooftrellen casting Overgrowth and Tidehunter ulti and Jugger ulti and lots and lots of ulties that happen not so frequently but make superb show and very pleasant gameplay.
2) No terrain and no kind of view-abstructers lead to movespeed deciding it all
Same problem like WOW had pre-WOTLK (dunno, dont play it now), where the one with most slow gets kill/gets away not killed. And most of time you wander around slow-mo, hoping your opponent is slowed even more. The one with more movespeed can kite and pursue, the one without can just hope he can 1-shot otherwise he's dead.
In dota, you had terrain, get up a hill and he looses the sight of you, you had a lot of edges, trees to loose your tailing person, you had blinking abilities on heroes and ground-targettable stuns, hooks and arrows to stop that. Trick as simple as get up the hill and use townportal, or eat a hole and hide in woods with tango - thats what makes the gameplay. In demigod maps are flat, actually EMPTY despite that great eyecandy backgrounds.
3) Same terrain and no kind of view-abstructers leads to abscence of ganks
Nothing like that great dota, where you can get from behind a tree, or from the river, or from the hill. Ganks make a great deal of gameplay, with heroes that are only good at ganking or rely on it to succeed, team hindering enemy carry by constantly killing him, lots and lots. Nothing like this here, you see everything around, you are almost everytime safe and can always escape someone trying to get you from the back, because you will see him coming.
Overall:
What we get is just typical WOW-like gameplay, slow and boring progression, where gear mostly decides, no tricks and agile-minded actions are required because there is no room to do them. No obstacles, all is clearly seen and visible, etc.
It would be nice if we would see a change in this, towards more fun, more action-filled and skill-filled gameplay like dota has.
