While there are a lot of ideas on the forum about how to adjust or tweak the different prestiges for commanders, i think this was overwhelmingly considered a huge success.
I love co-op mode, and this jump-started the game for me once again. Absolutely brilliant idea!
I hope the game carries on and is played for many years to come.
To more commanders, prestiges, maps and other content!
Agreed, there’s a couple of things I’d prefer to see changed but on a whole it’s excellent.
it’s excellente!!
There’s some prestige’s that are disappointing, like Alarak’s third talent, and the fact that you have to get the first two talents to get the third…Overall, however, it’s awesome!!
I think they did 4 things very well with the prestige system:
I concur absolutely and totally with everything said so far. Also I’m very happy to see people actually being appreciative of this. I think it’s super important to support and invest for more contents in the future.
I hadn’t logged on in months until now. This has been awesome. Plus there are a ton of new skills to master and ideas to be developed into new strategies. Been enjoying it. Thanks for your effort.
I’m sure more people would be agreeing with you if they were actually able to experience most of the new, fun content on limited time schedules instead of leveling up. 
But there is definitely fun to be had. Tychus may have an overpowered prestige or two, but at least he’s fun to level three times in a row since each one actually adds a whole different flavor of playstyle. We need more of that. I think less people would mind the grind if the prestiges actually altered the way you play to such a degree that going from level 1 again felt fresh. Few of them achieve that.
I haven’t even gotten a prestige point, but I’m enjoying the re-leveling. Playing brutal on lvl 1 with a lvl 1 partner is the kind of challenge I actually like. A lot more fun than queuing brutal+
Loving it also and making good combinations to counter mutations will be even more fun with all these new option. Good job and hope to see some new missions (and maybe Selendis) soon 
It has injected a lot of new life into co-op
My only wish is that we can choose the prestige order
Prestige is really great in idea. The part that soured my enthusiasm was having to level through 2 options that I didn’t want. I think if I could have chosen to only level the one I wanted I would be much happier with the product. The ones that still need work could have been attended to later and that would have been fine. Great effort but average execution by developers. Overall, a good system.
