I run a death/earth/fire mage and always run out of focus. I don't think the skills are too focus intensive, but that I need better gear! I think the potions are a good solution, but they take so long to use again. Frustrating when I'm waiting for enough mana to take out a troll, and I gotta rely on drinking 2 potions to get back enough focus to finish the troll off... so let's improve potions, allow us to consume them faster. But again, reading through this thread reminds me I need much better gear for my level, I've been using stuff from 2 years ago... time to upgrade!
