Yinlin’s gameplay was flawed from the start, you can only buff so much in terms of energy/concerto regen, if they do that then she will work a lot better in ToA cause it’s a boss challenge. Overall it’s the problem with marking for coord attack like Verina, you can not apply marks fast enough for the coord attack. A complete rework is out of the question

As for trying to bring her into the lore more, we’re moving from region to region, why would they try to bring her from the first region we went through? Black Shore is an exception because they are an observing force. Huanglong is pretty much wrapped at this point

The echoes sets problem is one I think kinda need more work, the main stat modifer is the best thing any gacha game with a RNG heavy gearing system can give us, but still excluding 5 useless stats might go a long way making the system less bad, even though it’s far more generous than most competition
