Tips for warding in League of Legends?
I have recently started playing support. So far I am doing pretty well supporting but I have trouble with one thing. How much gold should I split between buying wards and buying items. I start out with 2 wards. Then afterwards I buy like 3 wards at each recall. But my teammates complained and said I should be buying more wards than that. So of course I started buying at least 5 wards each time. But then they complained that I didn't have any good support items and that I should work on that. Well come on guys, I only have so much gold. And yes I do build the gold per 5 items. Typically philosophers stone first.
So my question is, as the support on a team, how much wards should i buy at each recall, or maybe what percentage of my gold should i dedicate to wards?
