Team help

Just wondering what you guys should think i should do next leveling and team wise.

Im using a slasher team right now and im all set to get mihawk my team without him is

4* arlong lv 33
5* ashura zoro lv 1
3* zuro lv 45
4* GP usopp lv 28
3* buggy lv 31

Not sure who i should level now cause if i pick up mihawk zoro will be wasted no?

Wanna hear your guys opinions
Future team suggestions would be helpful also

Or was thinking of just making my psy team already have

5* marco
Gp usopp
Bonclay

Not sure which one to farm for. Really wish i had shanks he would fit perfectly in both :'(

I would get rid of buggy over zoro, damage difference between the two of them is gigantic. On who to focus (besides bum rushing mihawk to evolved form) I would put more into arlong then zoro. There are plenty of slashers you might gacha that you can replace kuro with (such as killer, vista, lucci, crocodile, vista etc. etc.) while arlong will be the highest atk slasher for str. Also you can level up the zoro for a hopeful scratchman or law team from the next (I think?) batch.

As for a psy team, yeah those 3 are great, many of the best burst combo psy units are still away but will be available from event isle/raids (coby and garp respectively). Unfortunately until that island there really aren't any decent psy units you can get besides via gacha (Vivi is okay I guess but amount of leveling you'd need to do if you get from miss wednesday is horrid).
