With this spells I can gank first in lvl 4, after when I killed the whrats twice, so you can gank mid first. You need to back after gank, and buy the gold/s item as soon as possible. Now you can gank top, or mid, but I don't recommend bot lane, after you have a Giant's belt. If you bought that you can gank bot, and tanking the dragon. Then you need to help the worst lanes, and help your team with a lot of ganks. You need to start teamfights with your W-Q combo, When you buy the Sunfire you can diving easly. Alistar is hard to play in early, but you can defend the turrets, or inhibitors everytime when you need, and you can do very agressive ganks, with your CCs. Good Luck And Have Fun.!
