Leveling is up to you at this point, if you have the free time and the gold/plat to purchase the elixirs for the long grind then go for it. If you're lacking in an area, then I wouldn't bother. A date for the cap increase isn't set yet, so you still have time but we don't know if the update was submitted (or when it'll be approved) yet so there is no real way to tell how much time you actually have. I imagine that there are plenty of players who are trying to make the journey so you should have plenty of teammates to choose from. GL.

Sorry Necro, but I would disagree with you. Having all of the xp that you work for in the coming days/weeks reduced to 10% would be devastating imo. I would either go all in or fold early.
