If a game has loot boxes; I'm not going to buy it at all. The scumbag publishers don't deserve a sale or a +1 to their player count which they can smear in the face of their shareholders to show how successful their piece of shit is.
Loot boxes is bad enough as it's bordering on gambling but now that Activision have exposed themselves for essentially match-fixing and P2W matchmaking manipulation; it just shows a further despicable level of scumbaggery in the industry.
The sad thing is no matter how prominent this problem becomes; people will still throw money at games and companies will make billions. Until legislation is brought in which could take years and may not happen at all, it's only going to get worse and the best thing to do is not buy games like this at all.
Best just to avoid games form EA, Activision, WB, 2K and Square Enix. Now that lootboxes have weeded their way into single player games whilst using deliberately stifled progression to force users to buy rather than grind; it open the doors for more games to have such a system in place.
