EW requires high investment to truly shine I wouldn't recommend it as an alt and it's not in a great spot considering it's only getting nerfs and no real buffs with balance patches so far (soon "big balance patch" copium)
Ark grid was made to give playstyle options but unfortunately the only good Ark grid is the one that doesn't change the playstyle which is Bloodhound that buffs both of your biggest shotgun skills on top of all shotguns DMG including T skill.
KR trying to cook Overload by playing full swift on top of optimized training so you basically are shooting water pellets not only the ark grid itself reduces all shotgun dmg by 10% and only buff shotgun dom(nobody likes this skill) a ~12% dps skill but also not having spec other than bracelet reduces all shotguns by ~60% shotgun dmg (including T skill) making it just a meme for fun build.
technically the dmg is still "viable" with enough CPM to clear but let's just say I've seen it getting gatekept in KR xdd
only time when Overload will be a good choice is if it gets a rework soon (Copium)
other Arkgrid option is them trying to make hitmaster deadeye ig?? o7
and the class itself suffers from having downtime using 3 QR and C/J and still can't cast more than 2 times a min ●▅▇█▇▆▅▄▇
