1) Secondary? Which is best. I want to DPS and I plan only to play the Mage side. So for example if M/W is an awesome DPS Mage but W/M sucks. I don't care cause I would only lvl the W side but never play it end game.
For a DPSing class, you could go M/S, M/W, or M/Wd (not 100% sure on that last one). M/D and M/P are great soloing classes, but they aren't as good DPS-wise. M/K is fun, but again, it's not as good as the first three. And I haven't played M/R, so I can't say on that. But it's similar to M/K from what I hear - fun, but just ok dps.
M/S has quite a few ranged attacks, including a buff that makes shot do about three times as much damage as normal. Plus, they get a DoT and an attack speed increase buff.
M/W is the best for straight-out dps. I would probably go with this, if I were you.
Like I said, I don't know too much about M/Wd.
2)How high on secondary? (I know this will depend on the secondary so, please answer this based on your answer to question number 1) I realize that 70/70 would be ideal but, I have to be realistic. I have a full time end game character and this mage is just for fun (at least for now). So, "if" I wanted to play an end game mage how high would the seconary have to go to be effective? Remember I only get the general skills out of this
So, for example would 70/50 do it or 70/60 min??
Most people keep their secondary between 5 and 10 levels behind their primary. I would also say at least get it to 50/55 so that you have all your elite skills and you can throw any purples at them (HoS, HoDL, etc) If you go M/W, then you could technically just keep it at 50, since you won't be using their general skills other than Enraged, and the elite skills are dependent on your primary's level only.
I plan to play the game right and go thru the quests the way they were meant to be played, not hop over to CO and power lvl my character.
Awesome choice. It will take longer, but, imho, it's a much better experience than power-levelling through CoO. Good luck!
