Back to the game need help

Good morning guys, today I came back to the game, and need a little bit of your help to guild my main team. Also need some info about where to grind for the best equipments for it.
Here’s what I have rn:

Appreciate your time!

Can you show all of your Extremes as well? Also, there isn’t a “good” place to get the best equipments but I guess the “Equipment Collection” is the best way to get some of them. Some equipments you get from events or from the pvp.
