On team his role is utility dealer with good AOE. If you love going tactical with 3* you can keep him for his first and third skill even at 1/1/1. 60% for first skill is tolerable deal while third skill is easily good when enemies not having high debuff resistance / immune. Example strats is Taunt CE (to force him out after debuff) or LB Kaleido (for first turn AOE + debuff).

Cu Caster is better DPS than him, I doubt you wanted to replace the Irish Caster with him when it comes to damage dealt.
