I literally just threw a game because my game was lagging so bad and it was tight turn for time (was cycling murloc buffs) and the lag was horrible, culminating in me misclicking and selling an essential murloc (N00000OOOOoooo) rather than the primalfin i was trying to sell. It seems like this has been an issue for ages now and it is annoying. Its also annoying that they are not fixing it...like, hurry the fuck up Bliz? Whether you are buffing dragons, elementals or murlocs, the lag generated by the time you hit the end-game is horrible.
close and re-open the game, if you are lucky you'll re-enter the same game with WAY less lag ye blizzard fix shit related to lagging gameplay if only we'd get a -remove animations- options, just like how they did this year with -remove screenshake-
