For those who wonder if their +RES Ike is valuable

I finally made some calculations with my +RES/-SPD Ike to see if I can still use him although he has maybe the worst IV you can think of. The build I tested with was QR+Fury+Moonbow+Distant DEF seal. I only checked his baiting potential by being him the unit that is attacked.
It turned out that this Ike isn't that bad in baiting (even mages). He only looses to 15 natural build units and kills 128 in return which is quite a lot. Now to the specialized match-ups with the most threatening mages in this meta (with build tips from Guts ; no claim to completeness).
At first the hardest match-ups:
He can NEVER stop a Fury Tarja by baiting regardless of her IV or buffs.
He can NEVER stop Reinhardt by baiting regardless of his IV or buffs.
He CAN kill a L+D 3 Blade-Linde by baiting if she has no buffs. (Otherwise or with her normal build he gets killed).
He CAN kill DB 3 Delthea by baiting if she isn't +ATK or has no ATK buffs.
He CAN kill L+D 3 Celica by baiting if she is -DEF or -HP.

Now to the easier match-ups:
He CAN survive B.Lyn by baiting if she isn't +ATK or isn't equipped with Brave Bow.
He ALWAYS kills Fury Nino by baiting regardless of her IV and buffs.
He ALWAYS kills Blade-Cecilia by baiting regardless of her IV and buffs.
He ALWAYS kills Brave Bow-Bride Cordelia by baiting regardless of her passives, special, IV and buffs.

These results are quite unsuspected for me.
I only tested offensive builds on the attacking units - with defensive passives some of them might withstand Ikes counter. Desperation Mode of them also chances those results. But nevertheless a +RES/-SPD Ike is quite valuable on the battlefield!
