Do you ever feel like the amount of orbs you have is never enough

Not really.
It kinda depents on if you play other gatcha games.
As for me I play FFBE and Grand Chase too and there're completely other summoning system as in FEH.
FEH has a kinda unique summoning and unit system. Not every gatcha says that every unit is unlockable to 5 (or 6 Stars depents on the game) and isn't completely garbage.
4 Star Units are the most common in FEH meanwhile in FFBE the most commons are 3 Star Units.
In FEH you (probably) have more luck getting a 5 Star than in FFBE since the chance to get a instant 5 Star or a 4 Star that "breaks" into a 5 Star is very low (probably because there're 6 Star and 7 Star rarity).
So having 200 Orbs is, in my point of view, really much since you can get many units out of it, maybe not 5 Stars everytime, but you get units which provide you with resources and which you could possible make a 5 Star into.
That's why I like the summoning system in FEH, but the RNG (like in every gatcha game) is debatable.

*That's atleast my opinion. Everyone can have their own opinion on this.*

Theres no such thing as enough.

200 orbs guarantees nothing, but it will normally yield 2-3 on a legendary banner.

I do feel like I want significantly more orbs, but 300 a month is a decent amount to work with. It's... not really filling, the amount I can do with that much...not to me, anyways, but it does allow progress in the game.

You want a good grasp of how little 200 orbs can actually be? Take a ride on the Summon Simulator.

I cri evry tiem.
