History LowTierLetdown / Arknights

** Rosmontis's kit has aged rather poorly since her introduction. With the Flinger archetype's inherent flaw of being unable to hit aerial targets despite being a ranged class, it attempts to compensate by combining the Deadeye archetype's massive range and the Artilleryman's area of effect attacks, but Rosmontis lacks the high ATK stat that allows those archetypes to function despite their slow attack speed. This is supposed to be compensated for by the Flinger's attacks hitting twice, but this suffers against targets with high-DEF as each hit is being mitigated individually. And while Rosmontis's '''Armaments of Annihilation''' Talent attempts to help with this by ignoring a portion of her targets' DEF which is increased on enemies blocked by her Tactical Equipment, this value is flat, and while ignoring 160 DEF (175 at max Potential) was a decent value during her release, it is much less significant nowadays with the advent of more powerful enemies with far greater DEF stats. Rosmontis's kit itself has its own issues as well--while her S3, '''"As You Wish"''' has solid DPS in theory by halving her attack interval and giving a modest ATK boost, it's dependent on the deployment of her Tactical Equipment which require deployable melee tiles, limiting her own optimal deployment positions to places where melee unit can be deployed to block incoming targets. This skill also limits her to only attacking enemies that are being blocked, which presents a problem when facing enemies that can't or are too dangerous to be blocked, as Rosmontis will be unable to attack them at all. Worse, the Tactical Equipment can be deployed at the very edge of her attack range and block the enemy from outside of it, also causing her to be unable to attack them, making this ability extremely frustrating to use. For those who are unwilling to deal with the limitations of this skill, her S2, '''Nociceptor Inhibition''' is a much simpler option that gives her two more hits per attack and gives each a chance to stun at the cost of increasing her attack interval, but the DPS is significantly lower than her S3 and fares even worse against high-DEF targets. As a result, Rosmontis simply lacks the reliable DPS to be a practical option with extreme limitations on her best DPS skill, and with an increasing variety of dangerous aerial enemies that require strong ranged DPS to deal with, the Flinger's weakness is more noticeable than ever, making her a unit that is unable to handle more than moderately strong ground mobs in most cases. Her module does help her a little, giving her a third hit on each attack and improving her DEF ignore Talent, and admittedly this is a very good improvement on its own merit, but with the stat creep on enemies along with just how many powerful physical [=AoE=] units there are nowadays, many of which can also hit aerial units, it's not enough to give her any noticeable improvement in viability. Arguably the most damning evidence against her viability is that she is a Limited unit that only appears twice every year on various Celebration-series event Headhunting banners, leaving you with little wiggle room to actually have mere chances at getting her. Compared to W, Virtuosa, and Muelsyse (these three have been seen in the [[{{GameBreaker/Arknights}} Game Breaker]] page for this game), who are in the same figurative boat as her, she is ''by far'' the worst off out of all four of them. You kind of feel sorry for her...
** With the 5th anniversary comes what may be the final blow to Rosmontis, as the banner introduces Wiš'adel, the ''second'' limited 6-star Flinger, and with the reveal of her kit which appears to specifically negate all the Flinger archetype's issues as she has the ability to deal Arts damage ''and hit aerial units'', Wiš'adel quickly proved to be so absurdly powerful that she even managed to outstrip the likes of '''Surtr, Młynar, and Ch'en the Holungday''' in sheer raw damage output. And if that wasn't enough for Rosmontis, even her 5-star counterpart, Greyy the Lightningbearer, has been steadily gaining popularity since receiving his own module which gives him a significant increase in damage and reliability of his slowing Talent making him a solid slower/DPS hybrid. At this point, barring an exceptional Y or Delta module that could solve her issues, it is hard to see Rosmontis remaining relevant between her competition and difficulty to acquire as a unit.

* Generally, welfare operators (i.e. those obtained for free during an event) are considered to be poor outside of their own home field, sometimes even ''inside'', usually due to their clumsily-designed skills and/or talents that make them far too weak or [[SituationalSword situational]] for normal use. That is not to say ''all'' welfare operators are bad, but most of them tend to be. However, this is mostly a symptom of the earlier events, with some welfare operators (like Mint, Bena, Robin, Gladiia, Tequila, and Lumen to name a few) all being considered to be decent in comparison (and in the case of Gladiia, Tequila, and Lumen; [[GameBreaker/{{Arknights}} are quite exceptional]]) to some early welfare operators like Grani and Ceylon. Unfortunately, recent trends for the newly released welfares has been somewhat shaky, ranging from the rather good (Astgenne, Insider, Harold, Wanqing (Who is a [[{{GameBreaker/Arknights}} powerful support operator]])), niche/redundant but usable (Jieyun, Puzzle, Silence the Paradigmatic) and suboptimal (Vigil, Bryophyta, Lessing), with the latter being extremely unfortunate since two of the mentioned units are 6-stars.
