Yup. Typically someone buys a courier & wards at beginning. If tourney game Sight Wards (Basically Sentry) also for de-warding. 170g for courier & 200g for wards. Usually supports buy them since Hard Carries will be needing the gold more.
@ akts
You could argue that LoL made it a clutter. AP, AD, AS, Crit, HP, Mana, MR, Armor, etc...
But if we're getting to the point someone needs to have the fact Agility will increase attack speed which in turn (obviously) increases attack speed, then I don't think any amount of streamlining will make it easier. I just nejoy the 3 stat system much more, easier IMO.
