So, I gave myself exactly one role to try for FranDad since I lack a powerful ST Archer (Robin doesn't really make the values I need even at NP5, and Euryale is too niche for a general purpose ST), but unfortunately, I got the Doggo instead, and he's not tiered very great (Granted, no Avenger other than Jalter is rated highly, and that's because she craps out massive Tons of Damage that makes 'Zerkers envious, all without class advantage).
I'm still going to level him because he's a gold servant and my only offensive Extra class until next Halloween, but I'm not sure how to properly use him. I don't really have any means to support him damage-wise, since the only Servant I have that can is a non-max Andersen (and even if maxed, his time on the field is still very limited due to how fragile he is). I do like to think I have a bias/affinity for Quick teams (despite having no actual Quick-specific support yet; it's just my favorite type and almost all of my favorite servants are Quick focused), so at least he has that going for him for me, and he's supposed to be an ST burst Servant, which I very much lack outside of Brave Elly, Jack, and King Hassan, who is honestly more DPS than burst (Robin and Euryale have their issues at being reliable for that need as mentioned above).
So, any ideas or suggestions to optimize making good use of the Doge would be appreciated (mostly F2P player, so don't expect me to be able to bring in more than one strong support Caster at any given time, through Friends).
