How solos could work
So, you have said many times that you cannot bring solos because it has a negative effect on certain legends and the ping system, so here's my ideas to buff legends so they will work for solos:
Lifeline
The real problem with Lifeline and solos is her passive, so here's my idea to buff it: If knocked within healing range of her D.O.C. drone, and she has no living teammates, it will automatically revive her. This can be used twice in one game. She also can self-revive herself with her knockdown shield still deployed. Self-revive also takes 10% less time.
Mirage
His problem is also with his passive, so the solution is simple: self-revive while invisible. Decoy will also appear near him.
Wraith
Her ultimate needs to be reworked: Make her ultimate like Voidwalker. When setting the portal she travels into the void, but her percentage is constantly dropping (3% every second). In order to make this less op, people will be able to walk into the void and shoot her while she is setting the portal. This rework could allow for a lot of strategic solo plays.
If there are any other legends that will suffer from solos, please tell me and I'll find a way to change them to work in solos.
Ping System
So, I know the ping system is an essential part of the game, but the only pings I use are the "I see an enemy" ping and the "Let's go this way" ping, and I only use "let's go this way" when landing to see how far I am from where I want to land. But i understand the ping system is important, so here's my idea: When you ping an enemy directly, the ping follows them. When you ping a location, it tells you exactly what time the ring will reach that location. It will no predict future rings unless a survey beacon has been used.
Please consider these changes, and please bring solos in as soon as possible. Thanks.
