World of Warships and Battlefield 4 for me. I rage quit the least in these games so let's base it on that metric
COD MW (current one) can be good but almost every other round seems to have someone cheating/wall hacking which makes it not fun. ESO was also good but the without a ESO Plus membership and the crafting bag, it felt like a chore - and I couldn't justify the cost of ESO Plus so I dropped that one too.
