I played some AA, I dont experience the delay these other players are talking about however my client does crash from randomly every once in a blue moon. I do remember back in the day when I used shared internet I would crash all the time in crystal defenders for respawning with lag. It doesnt happen anymore though probably because I have my own personal internet that I share with no one. If you ever have a buddy streaming and downloading it taxes your signal to the servers.
From a person who plays lots of moba games, my tip to you "frames per second" and "ping" is almost everything.
Some of you players with lower system specs might be displaying lower frame rate therefore your computer doesn't process every little movement to show on screen = lag.
here are some tips that might help:
Try playing AA with low performance graphics and low bloom effect.
If that's not enough, make sure to turn off everything else like additional clients, anything that you are not using as those things will tax your computers processor while you play.
Make sure you have a stable connection. Don't stream or download while you play AA. Close everything that uses up any internet.
(sorry for you players out there who live far from na servers, by default your ping would be higher due to the distance)
Remember the Giant Scuba Moldie from the event? How EVERYONE was lagging? Because AA is similar where players clump and spam skills. Rose doesn't require a good computer to play. However in AA when you have tons of players spamming abilities and all clumped up YOU WILL LAG because it requires more out of your computer.
If none of my tips work, explain because I don't understand, lol
