we need better hot keys condrol UNITS menu Select the units or buildings you wish to have in the group using whatever selection method you prefer draw a box over the units left-click and Shift+left-click individual units Ctrl+left-click a unit to select all of those types of units in the main window press Ctrl+# to create the group and assign the # key to select it where # is the number 1 2 3 4 5 6 7 8 9 0 key for example like this game http://wiki.teamliquid.net/starcraft2/Hotkeys
Last time I checked ctrl groups where working alright. Shift+click is working with buildings. Box over units works, though it can be a bit temperamental. People need to settle down on things like this. These aren't necessarily bugs, but rather it is a lack of implementation (that is finished anyway). The basic things you would expect will come, but this is alpha. The game is faaaaaaaaaaaaaaaaaaaar from finished.
I really hope you're right about these threads being troll-made. If they aren't . . . well, let's just say we're going to have a rough beta--a rough beta with a lot of people asking why they have to control more than 50 units at once. At least this thread is asking for a good feature, one that we actually want. That makes it better, even if it's obvious.
