2 things...
Thing 1, engineers are working on that dreaded intermittent spinner lag, the "March 5th" lag... ugh, I know, they know, we all know we want it fixed asap!
Work-arounds:
Instead of waiting for what seems like forever for the spinner to get back a server connection, I log out and back in. I can load the game in 15-20sec instead of waiting ~2+mins.
This March 5th lag is really a problem during battle events. To avoid the spins, I keep refreshing the Rivals List (which pings the server keeping me connected) until I need to hit in BfEC or deploy in SA.
Thing 2, once we get out of this "fix-it" stage and everybody is fully updated with a smooth running game, etc... (yes, it will happen!) ...we'll get to better things, like Store improvements (not just new LEBs) and all of the other great QoL suggestions on our Wish List.
