A lot of different types of addons are doing exactly the same thing. For example, Cross Realm Assist was an cross realm addon but in fact it is an LFG addon with its own UI. Serverhop and WQGF were doing exactly the same thing from program logic perspective. Even Badboy as a chat filter addon would filter LFG spamming. The idea behind BlockChinese could actually be used for premade groups as well. There is no point for people to install so many different addons for doing the exactly the same thing. These features should share the same code base and work together.
Level your hero. You need to start leveling him from the moment you have 2-3 units. This isn’t necessary. If you have KotG, DH, BM, FS, or AM you don’t even have to wait for units. However, with the help of units, your hero can very easily overcome creeps. Among players there is a certain understanding – creeping. Creeping is the destruction of neutral units in order to gain experience. If you kill a creep you earn gold. A gold number and a plus sign will appear on the screen. Sometimes, you need to kill them in order to earn more gold for building purposes.
