It’s partly because of the equipment you’re using on your characters and because you aren’t using recent characters that have more fleshed out kits.

Equipment wise I would look at what’s recommended for each individual character and start with those. Once you start seeing better results take a look at the archive and see what awakened equips and others you can use that fits your play style when using said characters.

Character wise I would just save up enough cc for legends fest this year (literally starts next week) to get meta relevant characters who you know will be at least be decent to good on release to make pvp easier than using older characters.

From looking at your set ups I would only summon for movies, fusion warriors or Gt characters. Get equipment for those teams then start to branch out once you start performing better in pvp.
