20v20 on Asylum is fine just need some work on objective placements in it. Same with 20v20 Baylan works well compare to the 16v16 since both have enough room for more players to roam in.
I used to use Happy Landings 3 but I gotten so used to using Hard Landings... No animation drops is nice but makes me more squishy when comes from large drops though.
Working fine for me but all I can say is make sure steam is up to date... Otherwise some wonky stuff start breaking on steam from my own personal experience.
