Forum Discussion
Keep adding your feedback to their designated threads if you find new anomalies. Our only real weapon is comprehensive feedback. Yes, I may sound like a broken record, but the reality is that aside from being constructive pinpointing what does not work (without ranting and venting) and doing the bare minimum in the game, you have two other options: put up with it and keep playing a lot where our sanity will be questioned, or quit. Their Discord server also has a feedback thread that apparently gets passed on to EA. Drop the emotion, point out the obvious in a constructive manner, and do the same if they bring out any surveys.
EA should really provide some responses and what they are doing about the two elephants in the room but not holding my breath on it.
links to their feedbacks and aknowledged lag thread (creating new posts is pointless imo)
