The stuffs you describing was the main problem of the game, and why the pick rate was so heavily focused on few legends. And even if we forget the pick rate for a second.
Every single streamer was Path or Wraith, nothing else.
Every single tournament was 100% Wraith pick(its still is), and 100% Pathfinder pick(his pick is reduced and its kinda dependable on what your team style and strategy is, and its between him/Caustic/Giby). Now will can remove the Caustic after the nerf and put Revenant in there.
You are saying the game was fun ? But it was not fun for the players that were experience this completely OP mechanics, aka from the other side your enemies.
People were complaining hard time, because it was completely broken.
Again this game is about skill at the higher end. You shouldn`t be allowed to go 1v3 recklessly and have an ability to allow you to get out of trouble. This is plain bad and stupid. Its fun for you, but its terrible frustrating for the enemies and will just make them rage quit.
You can go 1v3 and still have fun, but you need big AIM and movement abilities, not an OP escape mechanics.
As far as just buff the others and let me catch Wraith and Pathy for example, this was impossible and the main reason was no other legends have such strong tools and no matter how much you buff them, they never ever will get a good pick rate, and never ever will catch Wraith or Pathy, or even come close.
Its because of their tiny and crazy movement animation hitbox and because of their kit, and that future such a strong out of jail self card, and such strong team abilities.
No other legends have that, so you can`t balance them.
As far as Loba, again you will not reward skill with his bracelet making her insta. And this will be totally OP and will make people get mad.
Why shouldn`t i get a kill on her, if i beat her on aim/movement, yet you want to punish me, who beat her on a aim/movement duel, and you want to reward her on losing the duel. How is that fair and fun ? Its not.
When talking about fun you got to take the view of both sides.
I get we get a different point and view on the game.So let`s just agree to disagree.
For me the game was insanely unbalanced in the first seasons and there was like 2-3 viable legends to play, now the situation is a lot different.
