The majority dont play for solo wins. You might want to consider that they play it for FUN. How can you think that the majority who gets trimmed by lazers to begin with have their sights set on solos when they cant even survive the lazers to begin with? Tying to make settings that bring about solofag situations has done nothing other that kill off maps. It just doesnt fuckin work, people have been trying this shit for years and it fucking doesnt work. Increasing boss hp/ decreasing zombie knockback/ bhop all increase team based difficulty, which means expect more losses and the remaining wins will be more team based. Increase individual based difficulty such as harder/faster lazers, and you slowly push toward isolating a map and making it less and less popular because it only appeals to a small selection of uber-tryhards. Best example of this was the minas fiasco, with all the "elites" leaving the server en masse on stage 8 because they didn't have 500 pts to get white knight, which was their key to soloing.
If "good" players think team wins are boring thats their own autistic problem. Getting a solo doesn't make dodging lazers harder, and the mentality behind this is literally "I feel better about myself because other people failed" rather than "I feel like I went above what I usually accomplish" If you want greater individual challenge you're best bet is to go onto the training maps or do minigames/surf/bhop maps or even play another game all together. Problem is, there aint audience there to show off how skilled you are, which is why they all jump onto zombie escape instead. Then they play the same effing map for years which they have mastered and when someone else starts to approach their safe space they feel threatened and worried that they arent going to be special anymore. Solos were never harder to begin with, they were a coincidence that got overhyped and now its meme status is just cancer with people purposely fucking over their teammates because they think it takes extra skill to do so.
God i wish rexy was back with his 360 lazer dodges. Actually i take that back, dude did a shitton of teamkillin with his pursuit of the solo too.
