When hovering over an ability, the tooltip will tell you whether or not that attack is weak or strong against certain pet types. Additionally, you can hover over the opposing team's pets and view their attacks during combat. This will be important since it’s a good idea to pit a pet that's strong against the opponent's pet who's vulnerable to that type.
Furthermore, we highly recommend you plan in advance regarding the class that you want to play. In the Classic WoW, there were no class specs. Every talent point spent couldn’t be changed without first resetting all of them and the talent point reset was a costly practice. If you already know what you want to play as in the end game – try to develop your talent tree accordingly. This way you’ll be able to save a lot of gold in advance.
Because the thing is, that sentence applies to both sides and it drives me crazy. Most comments about either Classic or Battle for Azeroth end up in mud-slinging matches for no real reason other then one side is being negative about the other side's favorite version of WoW. And the funny thing is, there are way, WAY more commonalities than differences in there, after you remove the ego of "my WoW is/was better yours sucks". In the end, no matter what anyone says, they are talking and arguing and fighting about it because they care about WoW.
For the duration of the fight, creatures in the immediate area will not be visible to you (but they may still attack you if they wander too close). Keep in mind that other players will still be able to see you and attack you if you are eligible for player vs. player (PVP). Other players will also be able to view your pet battle in real time, including the pets involved as well as their health as the match progresses.
This is definitely why we do a beta test. We can also do things like reset the realm at a busy time like 4:30pm PDT to try and find the source of a certain issue where a crocolisk is losing it’s brain due to how multiple processes are interacting and mirroring code to form a cohesive world. There were similar types of issues like this back in 2004 but we wanted to try and resolve this one before the weekend for the folks who are testing. (Blue Tracker / Official Forums)
Sharding eliminates server load and realm stability. Cross-realm sharding is here so that players are evenly distributed across realms and helps combat underpopulation. Sharding at launch is vital to ensure a stable launch of an expansion. Starting zones would be filled with millions of people and that would turn even accepting a quest into a nightmare. Disadvantages of Sharding
I recreated my very first character -- a human warrior, because in the last-push alpha test I joined in 2004, there was no Horde -- and logged in. Immediately, I was surprised by how good the graphics actually looked, for being 15 year old textures-on-polygons. Warcraft's bright colors and cartoony aesthetic continue to this day, so all the increased resolution and better-contoured characters in Lordaeron don't really change the game's visual aesthetic.
