Struggling to reach div 1
So most games I play are with either a 2 bar or 3 bar at max since I use data to play. I have been struggling to reach div 1 for quite some time now I always reach about 1600+ and then lose multiple games in a row due to cross spammers, even more op p2w squads and pressure spammers. I got the new vds but I felt like his performance was ass so I put in courtois instead. I want to play QC but my defence is way too high up and I can't really risk that since my internet doesn't help me switch to my defenders faster (pls don't roast for using LBC, I have to play this way to survive div 2) and it doesn't help the fact that some games my players feel like they ate a couple of burgers like rma hazard before playing. I would appreciate any sort of tip
