Echoes with matchups like this shouldn't be possible.

(with OR on several conditions) and get rid of your undesirable main stat echoes

I've been enjoying the hell out of WuWa coming from Genshin and HSR, so much so that I'm making sure to clear out my world's moonlit, void thunder, and sierra gale echoes so I have more to gamba gamba on. But when you get 3 cost echoes back-to-back like this it's just a feelsbadman moment. ._. I'm not petitioning to change the system or anything, just venting the frustration I suppose. Rng is rng. It is what it is. Back to echo grinding!

Gearing 8 characters with 5-Star relics/artifacts with the correct mainstar + set just 1 week after release is unheard of in other gacha games like GI/HSR. But here it can be done without spending stamina. Yes, the system needs a rework when it comes to getting exp to level and tuners to unlock subs. But the gearing process is flawless. It's been weeks of farming since Arleccino came out in GI and I have yet to see a single Crit Damage Circlet. Here? I have multiple Crit Rate/Damage 4-Echoes of 5-Star Rarity. All of that without using waveplates to get them. My Verina and Baizhi have full 5-piece healer sets with HB 4-Cost Echoes and Energy Regen 3-Star Echoes. My Sub-DPS are all geared with the Moonlit Set and ER/Elemental 3-Cost echoes. It's amazing how fast it can be done. Just use the databank, make a list of the echoes you need for each set and farm in the overworld. It shouldn't take more than 2 days of killing enemies non-stop to have a fully geared party.
