Are XP boosts worth buying?

Only if you're a smurf, otherwise there's no point. You need the experience, and you'll need even more experience afterwards.

Yes, especially when you're level 30

They halved the exp to 30. Just play normals and you'll get there pretty fast.

This guy made a video on it with xp boosts. https://www.youtube.com/watch?v=IpyRBnZq5GE

56 games. 36 hours. 54 minutes. This was after they decreased it. So it took longer before.

I believe XP boosts give you double XP, I'm not sure. Someone correct me if I'm wrong. So do you want to take 37 hours, or 74 hours? lol

wurf.

If you have less time to play matches, the faster scaling can help you get to the more competitive level, but generally is only advisable for MoBA players. The IP into runes starts falling short, the skill you develop is lessened and generally you find yourself behind despite being level 30 faster.

For levelling a smurf quick? Yeah They stack so if you buy both types and play games non-stop you can go 1-30 within a couple days Only issue there is that you'd lack IP for champions for ranked

Nope.
