First class to roll?

I am downloading Aion atm. If all goes good and i like the game, I do plan on dualboxing it. What would be a good class to roll first.... to eventually have if I do plan on dualboxing?
There is the the dual Sorcerer option. But the more I think about it, I am wondering if rolling a priest first would make a good combo down the road with a Sorcerer? You can never go wrong with a pocket healer.....but do these priests bring decent dps also?.....or should i just roll a Sorcerer and be done with it?
Melee is an option that i plan on playing with down the raod.....not now.

Anyone had similar ideas? And what combo are you going to stick with?

I'm only lvl 21 and dont know much about the game. It seems like boxing aion would be good to level but the flight in the game is going to make it impossible to pvp and maybe even pve at the end. Who knows but the flight is a big disadvantage to anyone boxing. I just decided to solo it and chose a sorcerer. Leveling takes awhile so I just plan on going slow.

I have a Sorc/Chanter (Priest) combo and it works out very well. Can duo elites this way fairly easily... Chanter tanks, holds aggro, heals... sorc stands back and blasts away. Chanters can meat shield it up amazingly well with decent gear.

I have templar/chanter duo I like - though it is low on dps - probably glad + chanter would be best combo but I wanted a tank mostly

I'm also having assassin + cleric as second pair for similar reason (less dps from cleric but more from assassin and more healing power)

In general I think a tank or healer is a good class to get there first (even though slowest) as a healer can always really help lower alts you'd level later - keeping xp of lowbie high (out of party heals)

Am running assassin/chanter at the moment. Great DPS from the assassin, augmented by chanter buffs and physical defense debuffs seems like a good combo to me.
