I got the same advice when I was leveling up from people, they said dont get tier 1 or 2 runes theyre a waste of IP
Kinda feel like those people are total idiots though, considering how insanely cheap t1 and 2 runes are and what a difference they'd have made when I was trying to learn how to jungle etc.
For basically the price of nothing at all you can get tier 1 runes in every slot and theyre about 50% effective compared to t3. they're actually a great bargain that help you not be at such a disadvantage compared to higher level players
