I actually remember doing this in the distant past around the first time SEGs came out.

Back at that one time, a "feature" nulled Beta SEC amps and after a certain point of killing back to back EGs, they'd get strong enough to require you to use a full-strength hit to take them out.

What made it doubly worse was that SEG appearance rates often fell as low as 1 in 6, so you'd be burning 5 elixirs to meet a SEG along with a few puddings to take out that SEG (highest event SED was like maybe 10m, average SED inhibition was 50m+) And as you know, SEGs pretty much don't give you enough pero to buy an elixir bundle.

Nowadays, I figure I can use that 30k pero and buy 3 R wilds instead of 5 elixirs (well, technically 33k pero if you count the conversion costs). I'm strong enough to weak 1-shot about 90% of my EGs and since I'm usually playing a few games at once, waiting 10-20 minutes helps me happily regen my focus and come back for more. End of an hour or 2 I drop back to the home screen and stare happily at my gift mailbox packed to 80+ rewards.

Not saying my way's better, and I'm not crazy arrogant enough as a paying player to think everyone can do this, as your event SED needs to be pretty damn high (~40m+) to be able to pull it off. I'm just saying that in the perspective of a heavy hitter, this approach is pretty "meh", as you can get more rewards actually taking out the EGs and not caring much for SEGs, especially when you have friends that actually share their SEGs to reduce the urgency of SEG eliminations.
