How to beat whaling

My solution is being poor. It works like a charm

I'm half Jewish. Never spent a dime on this game.

There's a very good method. Just think this:
-even if you spend money, you will just get a non-focus/other units of the same color or nothing at all
-even if you find it, there will be a new unit in the future that's better than the current one you would whale for
-with a little dedication you can whale with f2p orbs (just save them and dump them in one banner, many people +10 many units this way), it's more rewarding and less money consuming
-this is a gacha, so unless you want to spend money one big time to do something and feel accomplished for the rest of the game, don't do it: there will always be a new unit, strong or not, that you would spend money on

I am kind of a whale (Have spent around 2,5K€ in total I suppose) and let me tell you: Spending 100 or even 200€ (dunno how much that would be in $) on a single banner won't even get you far. With some luck you will get the unit you are trying to merge to a +3 or +4...
Especially this CYL2 banner is cursed for me, I spent so many orbs for only 2 Ephraims and 2 Hectors, damn you pity breakers!

1. You don’t
2. You can be content with what you have.
3. Luck

Not sure if I'll be able to help, but you might try spending more time playing characters you know you enjoy. Maybe replay some of the 5-map lunatic chain challenges (or 10-map if your team is good enough), or if chain challenge isn't your style, any currently available maps that provide a good level of challenge. Instead of "just being grateful for what you have," go actually enjoy it, and maybe you'll feel better about what you have.
