The quality of captured wild pets is random. As of patch 5.1, upon entering a battle the Pet Battle UI shows the quality of a wild pet (idicated by a color-coded border around its icon). If you're farming a specific quality, if you forfeit the match your team will incur a small damage penalty (roughly 10%). There is no accurate way to determine a pet's quality prior to the start of a battle.
I've been playing the Classic beta a little (and I do mean a little, the new Diablo season has me in its grips hard) and I can't see what the big fuss is about. It's Vanilla. That's what it is, that's what it was, that's what was expected and that's what we're getting. Sure there are bugs, upgrades some people didn't want and upgrades other people did want but didn't get, but in the greater scheme of things that's such a small part of the whole, it's barely worth talking about. So why are some people so insanely intent on ruining others' fun?
After choosing a race, class and customizing the look of your character, you will spawn in your race's starting zone, usually within a small settlement. Typically, these beginning areas are designed to get you to around level 10 before you leave and move on to the next zone. Right away, you will notice that some NPCs have a yellow exclamation mark () over their head. These symbols will also display on the mini map in the top-right corner of the screen if you are close to them. Talking with these NPCs will allow you to read and accept a quest they have for you. The objectives and status of this quest can be checked at any time by opening the quest log (L). Once you have completed the objectives for said quest, you can return to the NPC (or possibly a different one) to turn in the quest. The NPC whom you need to turn a quest into will have a yellow question mark () over their head. As you complete quests and your character gains levels, always be on the lookout for new quests being offered by NPCs.
This is, in my opinion, the largest change that WoW Classic will have over Vanilla, and it’s something that simply can’t be undone. Back in Vanilla, guilds were very secretive over strategies of how to correctly defeat a boss. Videos of boss kills were virtually non-existent,and strategies on how to itemize and play various classes and specs were hard to come by, especially for newer players. This, in addition to the unforgiving raid requirements and difficult content, lead to a lot of the player base never really getting to see a lot of the endgame content. Those that did rarely ever did so efficiently, and it wasn’t uncommon for the best guild on any given server to take months to complete a raid tier. There is absolutely no way that this happens in Classic. The raids in Vanilla are very much a solved system by now. Every raid, and every boss and trash pack inside, has been thoroughly strategized and talked about to death over the last 14 years. Rest assured even if you and your friends never played Vanilla, someone in your raid party will know exactly what to do on every boss, exactly when the trash packs are going to respawn, and exactly what buffs and gear to get to prepare. That certainly doesn’t mean thatClassic raiding will be a cakewalk, but it will be different than how the majority of people stumbled through the content.
Where to get materials and reagents you may ask? Buy for cheap off farmers in bulk or track Auction House lots. Get in touch with most big sellers. Communication is important here, send a whisper or write them a letter. It would be good for both of you to establish business relationships. Constant suppliers and buyers is convenient for both parties to save the time and effort.
