DA subclass~what works best?

Hey guys, finally getting close to my first sublcass. I have a DA, i was wodering two things.

1st, what in your opinion will be the best sublcass and why?

2nd. Say I use a bladedance, I get him to lvl 40ish, can I switch to my 75 da, and use all the lvl 40skills of a bladedancer as well as my da skills of 75? I have no clue how the sublcass system really works, so it'd be nice to get a simple summary by someone. I know, i did read the "subclass system" under library already. thx.

think of sub class as making an alt
instead of starting the alt at lvl 1 it starts at lvl 40 with all skills already learned
apart from the look of your toon and pk/pvp the 2 classes will function independant of each other

you change between sub class and main class by going to the head trainer of that race

so, if I'm a 76 da, with a subclass at 54 se, I wont be able to use any of the se skills as long as I am in da form? that kind of sux.

yeah kinda sorta but it would be unbalanced any other way
imagine if you subbed necro and had UD + transfer pain +anchor + silence + deflect arrow

lol I find 2 things funny:
1. You almost got your sub and don't know how it works.
2. You think DA and BD would be a good mix of skills lol:P

i wouldnt underestimate a DA with bd buffs

But if you could combine main and subclass skill DA and BD would be one of the worst combos.

When the subclass system first came out, most people thought this way. I know I did. I wanted to do a HE/Tyrant combo. Only problem would be mana.

Necro/SE/BD/Proph
