Neither my druid or mage have any energy problems even though I rarely use regen lix and never use pots. I've stopped using most lux regen items as well.
You don't really need more than about 6k base energy. With around 3k energy sigils the downtime is pretty short and I can spam 50 skills repeatedly.
On my ranger/war/rogue i find 1-3k energy is a good range and in combat regen a bit more useful, esp on mele because it's tougher to take breaks. I find myself needing energy lix more on them and often stack up as many in combat energy regen items as I can. Also i don't find myself needing much over 1k energy sigils on them.
Many people look just at their damage stat and forget about weapon speed or skill use. Being able to spam skills almost nonstop adds a ton of dps.
