this happens to me so much lol
i honestly stopped caring about it, and i make it work with the runes masteries and summoners i got
ending up with smite in the toplane for example well guess ill buy a cheap ass jungler item shit is actually not that bad because you get a pretty decetn item completed while they still havent got one yet and you can snowball off of that sometimes.
Only problem then is you can't tp bot and stuff like that, but you can be cheesy and smite their gromp or redbuff depending on where they start to ''steal'' the smite buff as it only has 1 per spawn so now their jungler goes to red low health is like FUUUUUUUUUUUUUUUUUUUUUUUUUUUUCK WHY DIDNT THAT HEAL ME which is kinda funny sometimes it sets them back a minute or so
i guess you have to be creative sometimes and work with what you got
