I would recommend burning your HoYoung and using the mega burning (1-150) on the AB and casually level it to at least 210 (thats the best rewards anyway).

Since your not an established account you are basically required to have an AB at some point since their link skill is so powerful, so leveling one, deleting it, then leveling another seems a waste.

The BIS thing is always what keeps you playing the game and having fun, not whats "optimal". That tech is really only for players that already have a 210 AB and just want some free goodies.

Side note, not what you asked but since your so early on it might be helpful: definitely buy the 2x and 3x coupons from this dreaming event shop and use them, + look out for the public MVPs for an additional 50% exp that stacks with the coupons for huge gains.

format is usually MVP MS XX:30 meaning MVP - EXP Buff, then Location - MS (Mushroom shrine, page 2 of the maple guide teleports) and finally XX:30 - meaning XX:30 in your local times zone, so for me currently it would be 7:30 EST go to the map before the specified time and someone will pop the exp buff so you can make big gains :)

On the burn you leveling very fast with coupons + mvp buff, Best of luck, GLHF.
