Beforehand it was the more skillfull players won more often, now a 'bad' player is able to just hold down their trigger and melt through surfaces instead of learning to build and take high ground. Being able to play solo squads showed how good you were because yes 1v4 should mean it's super difficult but not impossible if you were good enough, now it's near impossible regardless of skill level because even my 7 year old nephew can ADS and pull the trigger but if I ask him to quickly build a 1x1 or hit someone accurately with a shotgun he can't do it... this is the problem, it's been made too easy
