I don't need to do that.
All that is needed is that one commander benefits one player in such a way that they get an advantage by having said commander instead of other commanders. Even if 99% of all players suck at playing this commander and get worse results, it still stands.
Edit: access to variety is in itself a benefit.
Edit 2: you truly can't claim that you find this DLC-situation to be a-okay?
Then can we agree that variety doesn't equal strength? Or do I need to point out that you can use only one out of 3 commanders in the game and what you basically said applies to every single commander, including the stock ones and especially to the ones which require level to use?
You can't fully use your variety if you can't take more then 3 commanders, the final variety will always be exactly the same as your opponents. One out of three.
What new commanders do however is increasing the possible BOs and strats, expanding on meta, which I find good for the game as it keep it fresh and ever evolving.
We can talk about TA and elite troops, but that would only strengthen my argument as ET and TA are being brought in line with other commanders.
Then, if you take a look you'll notice that new commanders bring usually one specific strat/bo connected to this commander. They are pretty much one trick ponies, while most stock commanders are jacks of all trades and possibly the best doctrines in game are the stock ones everyone gets.
I'm not claiming the DLC thing is good or wrong, but I won't go apeshit, trying to convince others that earth is flat by saying "if we make enough rumble, the DLC will disappear", because they won't. This is how games and their expanding model evolved, you may like it, you may hate it, but you won't make it go away, unless some new, better for the companies method will eventually evolve out of them, then people will look back at DLCs with same pink glasses they look back now at expansions.
All you can do if you don't like DLCs is not buying them. It won't put you at any disadvantage, you will have few strats less and few colors less, but you will still be competitive with what you get on basic package.
I've got myself one skin and some commanders when they were on sale, costs of my game probably are about 60 euro and I have probably more then I will need right now, but since I like variety, I will get some new commanders(because I don't need nor want all of them). I've got my money worth of fun and will be getting it again.
Look back at oh so praised vCoH and its last expansion.
If it was separate DLC, one for additional vehicles, one for additional SP missions and one for additional mp game modes, would you get all of them? I know I wouldn't.
This is kind of freedom DLC allow over expansions. You pay for what you need and use and only for that. Again, I'm not defending DLCs here, just saying it is more player friendly model, unless you are a content whore who absolutely need everything for the sake of having everything.
Well, that ended up a bit longer then I expected it to be.
TL;DR:
-more commanders=fresh and healthier meta
-new commanders=/=stronger commanders, only different strats that can still be countered by vanila stuff
-I'm not defending DLCs, I'm just not deluding myself by thinking that if I bitch long enough, I will somehow make them disappear, this is what expansions evolved into, can't do nothing about it except not buying it
-I'm getting myself some DLCs because I'm willing to support company that provides me hours of fun and I like variety the DLC bring to the game.
-I don't need to buy content I won't even use, while I would be forced to pay for it on expansion
edit: regarding the hidden in store DLCs, they are not hidden as far as I know, its steam fuck up that was never corrected by them, they disappeared after case blue, shop was working fine before
