This game is very time consuming if you want to get everything but people still create alternate accounts. How much work do you put into your alt? Do you do the bare minimum to be able to host MP for your main account or do you grind the EX stages twice? What do you consider the bare minimum? Do you get frustrated when/if your alt gets better units than your main account?

I created an alt over a month ago. I was going to reroll since I had no ranged units to help with story but didn't really need the account so I didn't bother. Once Masamune rolled around I decided to have it host MP and not reroll since I had equipment tickets from earlier login rewards. After using the 4* selector I had core units Rahu, Lofia, Lucian, Zang, Caris. I farmed Elrike to 80 and also had Aruba, Margaret and Elibabeth as support choices. Most importantly I got Magnus and Albea to help with story. Got Shayna, Zain and Neica, now also have Dorothea, Aswald, Mei Fang, Reagan, Almira, Teona, Carol ,Yomi, Lucretia and a few others less noteworthy.

Having a lot of useful units is great but I don't want to farm and level all of them. I need to have some decent units that can clear content if there is anything I want to grind on SP. Also need to have good units to host MP so that they are useful. Top 4 are Neica, Zain, Lofia and Rahu but I'm wondering what other units are a must have for an alt. I don't plan to do Veda except for the first few floors. I'm considering doing Caris J but the drop rates are low and I don't want to do MP with this account but I'm using AP mostly for some unit shard farming so maybe just autoing isn't a bad option. How do you guys find that stopping point for your alts?
