I hate the endorsement system. I like the basic idea but to add a decay to it is the most stupid thing I have ever heard of.
They basically expect you to be the best and most awesome and friendly player every single game, cause if you go a few games without a couple of endorsements, you will decay and decay and maybe even lose your level.
I can't see ANY reason a decay system even exist. I get it if you get reported, but by just playing and not getting endorsements, it doesn't mean you are toxic or anything. If you find people who don't endorse ANYONE, which strangely happens, the system once again show how flawed it is.
I love Overwatch and I love my favorite heroes, which are all DPS. BUT since the endorsement system, I felt forced to abandon all my main heroes to ONLY play healer. Because healers get most endorsements BY FAR.
I reached endorsement level 5 last week (finally) and even now, I can't play anything else than healer, for fear of losing the level I fought hard to get
You simply can't reach and maintain level 5 by playing DPS, trust me, most people will prio healers > tanks > dps for their votes
