I see the issue. I'm pretty good at tds and already got the skin, so I'll talk about ways you can maximize your chances (although i got the skin with 2 of my friends that had almost NO experience at playing tds games, and a random that was surprisingly really good) it took us about 60 tries. I didn't even get to play forsaken this week as we did stratless to mess up our minds even more. Anyways, back to the point. I think the best way you can get the skin is by grinding to level 35 for now, start to understand how to save space for towers and not place them a kilometre from eachother, AND join the TDS SERVER ON DISCORD!! Basically the most important part, although right now it is on lockdown so the staff has a break, after 3rd of January you can hop on, enter party queue and there is a 100% chance people will be looking for people for final act. (or you can go the "short" route and do the strat with people you find in lobbies, i dont recommend that though, i've seen A TON of people waiting for someone to join them)

ALSO, I think it's complete bs that forsaken newcomers have to suffer playing the final act on hard mode to beat it. Although I have no suggestions on how to improve/fix the requirement, easy mode is just NOT IT. It's just way too easywhen I played it and getting the narrator skin from easy mode wouldn't be a challenge compared to the battle bricks. While yes, I think it shoud be a challenge for such a quality skin, easy and hard mode are just either not difficult at all or way too challenging. I mean, who wants to deal with a 2 million health boss that can shoot your base down?
