Well I go mine to 60 ‘legit’ started as affliction bit changed to destro recently. To be honest all specs are ‘Peasy’ - mobs offer little resistance……and that goes for any class.
Demo, unless you only do dungeons, then you want destro at least till improved rain of fire. Demo is good enough for ‘quest runs’ though. Just consider you’ll spend soooo much time funneling/draining back and forth.
If you want to quest, you take a felguard. Pure damage wise you’d take destro, but obviously you want to be able to cast and live when fighting more than 1 mob. Life tap and mana feed really made life easier, life drain will be your main attack next to wanding.
You can sarcrifice your voidwalker or felhunter to extra regeneration of health and mana. I never been able to get 5/6 mobs, as affli while leveling, usually they are too far apart, howl of terror sends them off where they then evade and reset, or they pull more mobs you didn’t intend. You are still squishy and I more often than not see the locks dying at the end of the line.
When you’re 70 and got gear, it’s easy, but yeah then you’re not really leveling anymore.
4 main dots for leveling are instant, what is the problem?
Only once I had to alter combo and add slowering curse on Shadra (lvl 55 elite spider in hinterlands) cause she obliterated pets.
