I currently have 7 characters total, will likely have 8 soon. But it depends on how you count it.

I have 2 'mains' - both templars but one with a "sensible" healer build for when I'm playing with other people and 1 who is a weird, complicated hybrid of everything I find interesting.

Then I have one character who is mainly a crafter (learning all the crafts), but does quests and explores for skyshards to get skill points.

Then there's my nightblade who I created mainly because I didn't have a character in EP, she's probably the nearest to a 'typical' alt.

I also have 2 mules - one for CE maps, consumables, clothing and other odds and ends and one for Glyphs and other upgrades, and weapons and armour I'm saving.

The remaining slots are used for characters I make for specific purposes, who usually get deleted after a while. I currently have one I'm using to try out the Thieves Guild and Dark Brotherhood who I'll probably delete when my sub time runs out. But I'm thinking of making a permanent sorcerer because I don't have one yet. Can't decide what they'll be like though so I haven't gotten very far with it.
