Rejoin tolerance

Been a couple months since i played overwatch or visited the subreddit, so forgive me if the following topic im about to discuss seems like a repost.

So, I used to have this problem before where I'd disconnect from the game from a random connection loss and would be not able to rejoin the game even though i had regained connection, resulting in a ban and ofcourse deduction from points.

Well, It still happens(even though the occurance is much more rare now) and i still cannot rejoin the game in-time because i am denied from entrance to the ongoing game via the "Rejoin Game" option in the main menu.

So here's my question;

What is the purpose of "Rejoin Game" when i cannot use it ? I have never successfully rejoined a game even to this day and I've been playing since open beta.

I would like to propose a suggestion or two to try and figure out how we can conquer this problem which is a pain for other fellow players aswell.

1- In game pause option. Yes, just like dota. The concept is simple, a player leaves -> game is paused for a minute and cannot be unpaused untill the player returns. If the player cannot return to the game then it is beyond the games current incapability to accept you back into the game. Therefore the problem shifts to the user's side.

2-More time for players to join. 10 seconds isn't enough, this isn't a speed run and everybody doesn't have a killer tower pc with ultra mega fast SSD's. Bumping it upto 30 seconds should be more fair than what it currently is.

3-I am not sure what's going on with the "Rejoin game" button so im not so sure what can be done to fix that. (It just dissapears sometimes and won't let you click on it most of the time).

I would like to hear more creative solutions aswell. Thank you for your time :)
