When you create a more popular and fun map ( i don't mean some stupid jokes put in the game with no common sense ) only then you can complain
you are wrong, man. let me ask you, have you ever complain a movie? then does anyone come and said to you "When you create a more popular and fun movie only then you can complain"? have you ever complain the food of a particular restaurant sucks? then does anyone come and said to you "When you make a more popular food only then you can complain"? that makes me lmao! I don't have any skills in cooking, that means I should respect every food including a sandwich that included shxt inside? rofl!
Btw, why should all the items be triggered? You want a laggy map with with even more laggier gameplay? 10 shiva's guards at once would cause a lag. Imagine if different triggered abilities would be cast from every item + all the 10 hero skills.
Triggered items do not make the game laggy, unless the mappers did not handle the triggers well (or bugs). Sometimes, the special effect / custom effect make the map laggy instead.
* Items - First of all it isn't just some random shit. They all are unique. And the descriptions are very easy to follow, making it easy to newbies.
easy for newbies? there are 4-5 levels of item combinations, compared to the maps which have lower level of item combinations, which one easier for newbies to learn?
items all unique? mostly are normal warcraft III world editor's built-in abilities with edited descriptions, names and numbering (damage, duration etc). anyone can easily create those "unique" items that you have mentioned, example: edit the name for "boot of speed" to "boot of GOD", edit the movement bonus from 50 to 51, edit the icon to a beautiful leg picture, then whoah, I have created a new UNIQUE item that never exist in any other warcraft III maps! lmao!
most of the spells in AoS have combo too, some also combo with items. its just the matter of learning those combos. you said the heroes of those maps sux probably because that you have not yet learned their combos. same as balancing, most of the maps also require you to play each heroes in the right way in order to "feel" the balance of the map. if you don't play in the right way, definitely you will think that the map is imbalanced. For example: First time you chose a strength hero "A" with low mana and you keep casting spells that require high mana, the result is that you cannot even kill any enemy hero. Second time you chose an intelligent hero "B" with high mana and you still keep casting spells and easily kill enemy heroes. and then you keep telling everyone that this map heroes are imbalanced because hero "B" is stronger than hero "A", the hero A's spell sucks. Actually the fact is that you played hero "B" in a right way but you played hero "A" in a wrong way. Talking about balance issue, I would like to point out the invoker hero in dota. Its spells are totally different with other heroes. The method of playing is totally different with other heroes. Do you think that is called "balanced"??
dota terrain is great? it does not even have a way gates or shortcuts like that. most of the AoS maps I played have a lot of hideout points too. so, terrain does not make dota unique at all. let's compare dota to the maps which have hideout points, "mysterious area" (some area which generates some special powers, for example: Anyone or some heroes who stepped into the "Blizzard Storm Area" will have reduced movement speed), places of interest (capture points to gain extra resources or places for anyone to capture neutral towers), way gates, elevated terrains etc, which terrain has better designs for full combat?
and one major weakness of dota is that, it focused on quantity (number of heroes / items) instead of quality. There are not much improvements on the quality of the map in each newer version.
