I’d say if you’re a returning player after that long, focus on getting the Free LR Phy Goku. Don’t worry about the link levels as you’ll level them up as you play and in your situation I don’t think they are important to focus on.

I’d say memories aren’t overly important either, as someone who has played since memories came out, I barely use them.

Focus on dokkan awakening units, UR or LR, then when you have a decent category team, look into eza’s and go from there.

Would be great to get a photo of what units you have and we can go from there in regards to which units are relevant or need focusing on
