1) All chat avaible (maybe only in Ranked and not in QM) the first 30 seconds of the game and the last seconds, because there are mannered players out there that want to say gl hf and GG.
2) A vote to kick button : there are alot of players that THINK they are lost and then start feeding themself or just do random totaly no logic stuff to lose the game faster.
3) A ban option in Ranked play , atleast 1 hero or just like in tournaments 2 heroes.
4) New heroes banned for the first week in Ranked play, Ranked is no place to try new heroes In my opinion.
5) Voice chat communication (in ranked atleast).
6) A little more time for the draft (from 30 to 45 or even 60 seconds) because you can't communicate properly with that short time I prefer to be a little longer on the hero draft then lose the game because people just took a hero to have one because of the short time and low communication.
7) When selecting a skin or mount in a draft a little pop up from the skin and color change.
8) MMR stats viewable : there is nothing so sweet to compare each others MMR.
9) Add Leagues or something simular: I have the feeling rankend isn't special at all , playing with a number 1 like 1000 other people isn't special, why not add some leagues Blizzard has such good ladder system in StarCraft2 , sites like sc2ranks.com and nios.kr and so on will be coming to Heroes Of The Storm asswel because of that.
JUST SOME CHANGES
1) For the first game and win add 50% more gold so instead of 30 it will be 45 (only if its the first game and a win), its something extra and a tryhard motivation.
2) After playing the Alpha since now I just can't get used to the right minimap please make it moveable to the left.
3) In the replays see what your enemys said and pings (with a vision select just like in SC2 replays).
4) with the master skin 25% more exp (maybe gold) earn and 5-10% off other skins.
5) for atleast the Legendary skins a new portrait.
