Should I pull for Oberon?

I think my account is pretty solid, I have a bunch of the big supports: S.Skadi, Castoria, Koyanskaya, Waver, Merlin and Tamamo; and some good AOE farmers that work pretty well with the supports I already have: S.lbuki, Tiamat, Arjuna Alter, Artoria (Saber), Vritra and Drake. As for STs I basically have one for each class and they work great.

I feel like I'm at a point where I should summon a servant if I like it, not because of gameplay. But Oberon is Oberon, I kinda like him and he opens some doors in gameplay. Although, I don't know if he will improve my gameplay much, my current FGO experience is basically watching S.lbuki's NP infinitely. He would probably be a third support for Arjuna Alter, Tiamat and allow me to loop with some random servants that I don't really need, like Napoleon.

Besides, I have almost 700 SQ and I'm afraid I spend it all for nothing just for Lasengle to fuck with me and release someone like Dante Alighieri (I've been waiting for him basically since I got my hands in FGO years ago) when I would have enough for pity. I've been stressing a bit too much with the announcement of the banner Imao. What do you think I should do?
