So considering I have a lack of servants, I happened to get Medea, looking at her placement in the tier list she seems like a good DPS, should I level her up or just stick to Cu Chulainn Porto?
It is useful to have at least one strong servant of every class, for farming and class specific boss fights. Since she is a good and one of the few single target casters, even among the 4* and 5* servants, the exp wouldn't be wasted.
I would actually prefer leveling FSN Cu over Cu Proto.
Some 3* servants to look out for that are useful even at endgame.
Saber: Ceasar
Archer: David
Lancer: either Cu. FsN defense Proto for slightly more offensive.
Rider: Ushi
Caster: Hans fantastic support. Medea
Assasin: Cursed hand is the Cu of assassins or Fuma
Every servant can be used and there are many more 3* that are even better choices.
While I'm sour on dps casters in general (berserkers tend to outpace them even against assassins for offensive firepower), Medea is absolutely worth levelling because she can np often and her np does buff removal which is super handy especially against demon pillars.
She 100% deserves that high tier list placement. Just not for her damage but more for her utility.
