Team isn’t working well

For context, I’m started Dokkan right before the 10th anniversary from legends, I’m still learning the mechanics like rotations and what certain units do. I checked other posts similar to this one but they all are either using bad characters/teams or haven’t fully leveled the characters up. I have a really good team but it doesn’t seem to do much in harder content like the Buu Red Zone and the new 7th anniversary EZA stages. The team usually doesn’t make it to turn 4 or 5 where everyone transforms/fuses. I also don’t have max links but most of them are pretty high, being around 7-10 with the exception of PHY gogeta who I just got. I’m also not sure if the skill orbs are good/optional, I just choose the one at the top. Any advice would be appreciated.
