More characters should = less healing if none

Ive been playing dp alot and holy every time i see a recoom,videl and roshi i roll my eyes because they always have a 5 character dp team which is exhausting to fight when i mostly only put 3 on my team they always have an advantage you shouldn't be able to heal ur characters when u sideline them if u have more than 3 characters it would make dp so much more fair and have more variety character wise online
