Regretting characters

Is not fair saying "I regret 1.x unit", when probably that character carried you for 3-5 months after actively using it, and highly probable you were 100% aware who, and why you were pulling.
I mean, I almost always seen ppl enjoy their Seele destroying all the contents in the first year. Now she is weak, and these ppl regret pulling for her?
Im sure that there are players that have fallen in the hype, in the "she is future proof" or in the Rerun trap, but I see too many Seele and SW in the bottom of "I Regret" list.

I pulled SW and Jing Liu, I completed a lot of contents thanks to them, but I can't say "I regret JL/SW" only because NOW they are weak, after she carried my account. Let's not lie to ourselves
