About the arcade missions

no, when the missions are done they are done.

If you bought one of the passes, there are daily missions that'll pop up, but for free players theres just the veigar line and the blitzcrank line and then you're done.

So the missions are just another milking tool for Riot. I get it, they need to make money, but i was specting simple missions like every other game has, like win a match in Twisted Treeline, Get a double kill on a match and things like that. You could win IP or essences, but no, just for events, to win summoner icons that nobody uses anyway. Riot has mastered the ability to screw good things, just like the custom maps, that we can only play when they alow us to play. No wonder why any new trending game surpasses LoL, like PUBG just did.
