Build on strength or focus on weakness?
Do you tend to rank up and use resources (ISO, catalysts, gold) on your top tier champs to Rank 5 before ranking other top tier champs? Or do you try and get all top tier champ to a minimum rank?
For example, would you rank an awakened NF to Rank 5 from Rank 4 or get an awakened Aegon up to Rank 4 from Rank 1 first?
