Expand immediately. Creating a base expansion at another gold mine isn't a luxury in World of WOW WoTLK Classic Gold Warcraft like it sometimes is in other RTS games--here, it's a necessity. As soon as you kill the creeps around a mine (if there are any) and you can spare the resources, send a worker to construct an expansion at the mine. In multiplayer, it's a good idea to have an expansion at least under construction, if not producing, when youlow upkeep. Two expansions is a good rule for high upkeep as well. Just because you're hoarding gold, don't be miserly with it. Spend, spend, spend is the rule--you should have buildings, units, or upgrades in progress at all times.
Use groups and subgroups.
Use groups and subgroups. RTS veterans will already know this one. You can assign up to 12 units to a number key by selecting them, then pressing CTRL + number, and then hit that number key again to select them. So to assign a group to your "1" key, select your units, press CTRL + 1. then select them at any time later just by pressing "1." Learn to assign similar units to one key for easier access and control in battle. For instance, you can put your heroes on one key, your melee attackers on another, your ranged fighters on a third, and your spellcasters on a fourth. Mix and match as needed, but don't use too many groups or you may get confused. You also have subgroups, which consist of multiple groups within a defined group, in World of Warcraft. Subgroups are visible in the unit group display as the highlighted group of units. You can switch between subgroups with the Tab key, and holding down Ctrl will let you issue an order to only one subgroup. In this way, you can have multiple types of units in one group but still issue commands to them discretely. This also leads us to the next issue.
Master the hotkeys.
Master the hotkeys. This can't be stressed enough. You can do everything in World of Warcraft with the mouse, but in the heat of battle, you really don't have time to be clicking every button on the interface repeatedly. Selecting your own units can be done much more quickly with the keyboard than by hunting each one down with the mouse, so use this to your advantage. Likewise, you can move around the map with keys. For WoTLK Gold example, the space bar will take you to the last announcement that was made, such as an upgrade being completed or an "under attack" warning being given. Each unit and building command also has a hotkey associated with it. Hitting the C key for chain lightning is much faster in battle than hunting down the icon in the lower right and then moving the cursor all the way back up to the battlefield. Also, if your spell-casting units can auto-cast spells, like the orc shaman's bloodlust, remember to set your spells on auto-cast by right-clicking the ability icon in the command window. Deft use of the hotkeys, coupled with a solid strategy, will win every time.
