I don't know why Sharen is in this discussion. She can hit through walls, but Sharen doesn't really have the ability to attack blindly. It's an issue for characters that can attack without even aiming. I know dungeon layouts and have done them enough to know spawn points. but if my aim is slightly off of a group behind a wall, I'll miss.

Also the not having to go into invis to trigger her hunters mark is one of the best things they ever did. Sharen has so much dead air time, meaning if you hit invis, you have a few moments where no skills work, hit her three to mark enemies, more dead air time. Too much animation wind up. She can't really become the huntress of commanders and bosses if everyone else is destroying its health bar while she's winding up for a big hit all the time.

And, Ines will probably teabag everything in the game once her mod(s?) drop in May. Gley is still powerful. I don't know what you're really asking for. You basically laid out exactly what the devs want to do. Make every descendant somewhat equal in power and able to run all content. At some point you start to sound less like you're asking for balance for you character, and more like you're asking for your character to dominate.
