How is that a good point to make though?
Like, I can understand if someone actually does like Soldier 76 for his relative normalcy that acts as a point of contrast to the rest of the cast
or just likes his effectiveness in battle
But why would anyone defend him on the basis of "Yeah, he's a total generic, unoriginal, cliche. They intentionally made him super lame, gg blizzard"?
In all fairness, all of the characters could be extrapolated into being archetypes. Soldier 76 might be the most archetype-y of them all, perhaps, but you can't shit on him for being "generic" (which I completely disagree with btw) when all the other characters are just as generic as he is. Because if you want to break it down, it looks like this:
Soldier 76 is the grizzled war veteran.
McCree is the badass yet chill cowboy.
Genji is the honourable ninja.
Pharah is the duty-bound soldier.
Tracer is the cheerful, joking team member.
Reaper is the edgy badass.
Bastion is the gentle giant.
Hanzo is the honourable samurai.
Junkrat is the crazy arsonist.
Mei is the environmentalist adventurer.
Torbjörn is the bearded engineer dwarf.
Widowmaker is the femme fatale.
D.Va is the cutesy girl.
Reinhardt is the chivalrous knight.
Winston is the super genius animal.
Zarya is the female Eastern European weight lifter.
Roadhog is the mercenary who relishes in what he does.
Lucio is the freedom fighter.
Mercy is the pacifist doctor.
Zenyatta is the wise spiritualist monk.
Ana is the sassy old lady.
Symmetra is the perfectionist seeking order and structure.
As such, Soldier 76 is just as generic as every other character in the game. He might have the most straight-forward gameplay, but not every character has to be a unique snowflake with in-depth mechanics in the game. I'd even argue that the fact he has the healing field makes him already more interesting than "guy with a gun who shoots things", as well. And lore-wise, I would argue that Soldier 76 might just be one of the most interesting characters as well.
Basically what I'm saying is: While all the characters in this game might be walking archetypes, it's what Blizzard does with them to make them unique. And frankly, I feel like Overwatch's roster is one of the most unique, easily recognizable rosters in almost any game ever.
