The choice depends a lot on how far you’ve leveled up these heroes. A fully developed 3* is likely better than an early-stage 4*. Without knowing how far your heroes are developed, it’s hard to judge. You mostly have a solid group. Rigard is your only healer, so he’s going to have a place almost everywhere.
Some thoughts about building a Titan team, greatly informed by the wise posters in other threads:
- An optimal team has a mix of skills. Deviation is common, but it’s best to know why you are omitting one or more of these:
A. A special that reduce foe’s attack or (better yet) defense,
B. A special to increase your team’s attacks
C. A healer
D. Some bite to deal serious damage
E. Ideally someone to remove foe’s buffs - Your team will evolve over time.
A. 3* heroes are pretty easy to get to max. It’s not a bad strategy to build a solid 3* team before starting on 4* heroes’ development.
B. 4* require a lot more feeder heroes and some rare ascension loot.
C. 5* require a mind-boggling amount of feeders and very rare ascension items. I strongly recommend holding any of these you draw (happy day!) until you have completed a solid 4* team. - Ideally you develop some depth on the bench. There are five colors of titans, and ideally you’d have the bench to swap out the weak color against the Titan for the strong color. For example, on a red Titan you’d ideally want to double blue and omit green, while against blue you’d omit red and double green. (Some triple or even quadruple on the strong color.) Balance considerations may push against this ideal.
