You should pay me real money to play this game or advartise me at least , because i spend 13 000 in this game I'm playing it since the begining and still going in would be nice if you Value your long time players like my self who invested a lot of time with some special unique rewards , so we may feel special regarding this.
The game is nice , always addapting never the same making it a huge challange the fact remains is that Valve don't care about long time users of the game AKA "players who invest a lot of time and dedication into the game".
The real problem with dota however is the fact that Valve will never ever advirestise their game anywhere unlike their competition Leage of legends , as we can see LoL is a far superior game when it comes to geting new players into the game , It's fairly simple to learn and hard to master.
They also invest into side projects like : Music videos , comics etc. I would highly advice valve hire me as a project manager on to their company because , I have spend a lot of time playing Moba games and with my knowlage of the player base I can easly say that dota has a HUGE advantage over the other mobas in a sence that the game is the original MOBA experiance , I know how to hit the targets regarding this , I know for a fact Valve won't care about my comment or my suggestions regarding the benefits of the game , also to the people who would say that dota is dying are wrong we always stay at a very stable numbers they don't decline they are just going up and down all the time because people get bored of the patches and try something else , like the new patch 7.23F which got a lot of people back to the game with the new content it was with the jungle items.
My ideas to make Dota2 more positive is to :

1 - The game is stable , patches are coming in hot and fixes are almost instant , however there are many other quality of life changes that need to take place.

2 - A better learning curve for new players that will try the game , for example - It would be nice if higher MMR players can assist the lower mmr players , such as Immortal 1000 rank , who can recieve non-tradable items like bundles of sets etc.

3 - Make Dota+ more open with more rewards - Make dota+ with more rewards and more active surge lower it's cost and make it so everyone can afford it , I'm a dota+ subscriber since the begining and I know for some people dota+ is expensive , because not everyone comes from a rich country totaly understandable , so please put it into considoretion regarding this.

4 - Smurfing - This is a topic that will not only be a real problem for newer players , but also a huge problem with lower mmr games , Make the rank entry level at least 50 - 55 which will take at least 2-3 weeks to play and another 150 normal games , I have high rated players as friends and I can't even describe how easy it is for them to smurf and ruin the experiance for new players.

5 - Toxicity - Ban people from ranked games where they feed intentionaly!!! Very Very Very bad and very infuriating to see people who are lower mmr and don't know how to behave , please make Behavior score more viable and harder to earn!

6 - Marketing - Make more platforms , make more Dota2 related stuff , try entering the mainstream with TV shows , comics etc. advertise the game more , so we may get more players for the love of god , please INVEST MORE MONEY INTO THE PRODUCT YOU HAVE AN AMAZING PRODUCT advertise it everywhere!
