I'm thinking along the lines of skills like magelight, expert hunter, bound armor, inferno, etc, anything that passively grants a buff for being on your bar.
The skills could have toggle-able permanent visual effects - it would not affect the casting animations, but rather add unique animations for being on your bar.
Perhaps glowing arms or a glowing torso. Maybe give the classes that have such skills unique visuals for them i.e. inferno could make the caster look like they're on fire for having it slotted, or perhaps leave flaming foot prints on the ground. Bound armor could literally be a set of summoned armor like it was when the game launched.
Again this would all be toggle-able so if you don't want it, you could simply keep the feature off.
Add a Scribing skill that works like Arcanist beam.

Veteran players have been alienated and disengaged from Overland since One Tamriel, due to the lack of difficulty, and pushed into dungeons and trials; the minority of content in the Elder Scrolls Online. We can't take the repetition anymore, fix Overland engagement for Vet players. I don't even care if it's not combat related anymore, just make Overland engaging again.

Overland difficulty scaling is desperately needed. 10 years. 6 paid expansions. 25 DLCs. 41 game changing updates including One Tamriel, an overhaul of the game including a permanent CP160 gear cap and ridiculous power creep thereafter. I'm sick and tired of hearing about Cadwell Silver & Gold as a "you think you do but you don't" - tier deflection to any criticism regarding the lack of overland difficulty in the game. I'm bored of dungeons, I'm bored of trials; make a personal difficulty slider for overland. Make a self debuff mythic. Literally anything at this point.
Should skills that give special effects for being slotted have toggle-able animations/visual effects 12 votes
