For anybody not familiar with the"Pre-Patch" term, it is the patch before a new expansion goes live. During pre-patch, each one the substantial system and class changes will go into effect, and normally, there's also an event which takes location and is only accessible during pre-patch wow classic gold. This time around, all character levels will be squished down (max level until Shadowlands goes live will be 50), all corruptions on equipment will become inactive, and also the course talent and skill changes will also go live. However, the Center of Azeroth Essences and Azerite Gear Talents won't become inactive until we head to the shadowlands.
In addition to Shadowlands growth changes going into effect, the pre-patch event is a scourge invasion. Although this is going to be the third largest scourge invasion longtime players of WoW will have noticed, it is just the next time Blizzard has completed a zombie infestation as well. The infestation is simple because NPC zombies will attack and may cause players to get a debuff on these, which, as it reaches zero, will subsequently turn the participant into a zombie and infect other players. There are also plagued roaches, which, when they're killed, will also lead to the player who murdered it to find the infected debuff. As a zombie, players get a whole new set of abilities to use, and it may be a lot of fun running in Stormwind or Orgrimmar. Obviously, when most this went live on the PTR, it caused no lack of consternation among gamers.
The main issue is trying to do anything that isn't the zombie infestation gets challenging to perform, mainly since player zombies like to hangout at quest givers and other spots where plenty of gamers tend to gather. Because this event also will come with an entire questline that takes place in the zones around Stormwind and Orgrimmar, there's ample opportunity to camp out and possibly infect as many players as you can. However, one positive change from the last time the zombie infestation occurred is that Blizzard appears to have made it more difficult to disperse it into the rest of Azeroth. Among the first things I did when I got infected was to hearth into Dalaran, but when I arrived, I was not infected anymore. However, I managed to carry it to Boralus through utilizing the portal in the mage tower, so it's not a perfect system yet.
The major thing to understand is two distinct events are going on. There's the scourge invasion as well as the questline, which takes players to Icecrown and sends players on a goose hunt for Nathanos. Then there is the zombie infestation, which adds a small PvP aspect to everything. It isn't surprising some folks would want to get involved in the first event but not the moment, as not everyone likes PvP or using their course and race skills taken away and replaced by other skills. Blizzard could make the infestation only active for a few of those weeks of the invasion, but that's no fun for anyone who misses that week and would want to engage. Honestly, the best solution probably is to leverage the Warmode system buy Burning Crusade Classic Gold. An infestation is basically a PvP event , so being able to opt-in with Warmode makes sense. Even doing something at which for the majority of the invasion, gamers had to opt into the infestation by choosing Warmode, but at the last week, even before Shadowlands fell, the infestation could affect everyone, would most likely be the optimal solution.
