Wellstring is just sort of weird. if any bow/flux player were too add it to their weapon pool i wouldn't question it but calling yourself a wellstring main seems like a bad idea. it has this problem where is can theoretically be really good if you practice with it, but you could also practice with normal weapons and your results would only be slightly worse, but more versatile as the meta shifts.
Onto the weapon itself, it feels like it wants to operate in a similar space to dynamo, which is kind of a surprise for a weapons defined by its relation to chargers. acting on the midline is a unique place for a stringer, and i think it does it about as well as you could get without just making bamboo 2. Taking advantage of partial charges is very cool, but like i said earlier, instead of learning to play around it you could just play a charger and you wouldn't have significantly worse results while having a more useful skill.
There is defiantly something to be said about its role as a training tool for partial charges though. having played a lot charger i can attest that partials are key, and when i started useing them consistently i feel like my skill shot up(especially when i switched to c-liter, as its longer charge time means you can get close range full charges as easily). For that, wellsting works, but its more applicable to bow rather than chargers in general.
For the more general use of wellstring, its very good at being annoying. its wide arc of bombs, while not super threating, can be a very good deterant for a very large area. and with how quickly it can get them out, it could esily support the rest of the team with 1 or 2 shots. This also gives it alot of paint, which gives it high utility in SZ and in pushing the team forward(as TW but i dont care about that), as giving that much space to move is inceadibly valuble to the team.
On the topic of the kits, both of them kinda suck. V wellstring has the betterm kit, but i think c wellstring has the better idea, as wellstring really leans into the supportive side of bow, its just that detection is not very useful, and point sensor has a bit of antisynergy with wave breaker, which majorly hampers that kit. v wellstring would work better if ultrastamp was at all functional, but i understand nintendos reluctance to give this a good special. Wellstrings high paint means it has quite a high special output, so if it had a usefull special like zooka or cooler, the meta would be in total dissary, which i dont think nintendo wants to deal with at this point in splatoon 3's life cycle(i think the time should be extended but i understand why nintendo has it this way).
(i did not accedently post this halfway finished then edited it to have my full thoughts that didnt happen at all)
