Well, at first, I bought heroes with rp-only the ones I liked a lot when they came out on sale. That was until I got a nice all-around pool of heroes. Then I started buying with ip and saved the rp for other purposes (skins on sale, mystery gift with friends/on self etc).

From a point onwards though I became a bit..hesitant on spending ip if I hadn't much. So, I felt "safe" if after whatever purchase/consecutive purchases there was the "safety net" of at least 10k ip-that I didn't fell below that. Say for example, I wanted a hero of 6300 ip worth. I'd unlock him after I went to 16300 ip at least.

Now that I have most heroes I want. I just kept saving-was looking for some 6300 ip worth (and a lot of lower cost) and some runes as well. But as I said..Braum will probably be insta-buy (even at >7k ip) ;)
