https://zero-k.info/Battles/Detail/2425264 - this seemed fine for frontliners? You had one backliner. (trollbot backlined)
https://zero-k.info/Battles/Detail/2425279 - you had three backliners, so 4v5 frontliners. (ruru, trollbot backlined, vxd air)
https://zero-k.info/Battles/Detail/2425282 - early exit
https://zero-k.info/Battles/Detail/2425292 - two people rushing singus and then a nuke at the back (trollbot and imbombu). A third (ruru) backlining. Opposing team also had three backliners (824654 with army at back and fusions, psaniac on air, chonky with GS).
https://zero-k.info/Battles/Detail/2425292 - trollbot backlines flooding dirtbags to the front while slowly building singu. Ruru backlines as air. Ibombu makes units this time. Chonky backlines with GS. Opposing team has two backliners making this 6v7 frontline.
https://zero-k.info/Battles/Detail/2425304 - You instant resigned.
Okay so basically some players are mostly doing the same thing every game. But with players this consistent their elo is based on them playing the way they do, which means teams are balanced around them playing this way too. I didn't feel these games were unwinnable.
To be clear, I empathise. We can acknowledge that the way some players play is frustrating while also realising we can still play around it or avoid it. The players you're consistently struggling to play with are chonky, ruru, trollbot, I_bomb_u. If teams are small and there's a critical mass of these players, maybe avoid? This is especially the case in small teams where they're required to hold a front to not autolose.
As for playing around it, I found that I struggle a lot less when I settle short of the 50% mark on the map and wait for my team to catch up. I play positions where I feel comfortable 1v2 or 1v3 because I know I'll have to pick up some slack. These players usually contribute eventually if you give them the space.
