I'm wondering if I should get Classic, GvG or TGT. I opened a lot of classic early and have some of the good neutral legendaries (Sylvanas Windrunner, Bloodmage Thalnos) but I also have some crap ones (Cairne Bloodhoof, Wilfred Fizzlebang, The Beast). I also have all the Naxx, Blackrock Mountain and LoE cards. 

Anyway, I've never purchased cards from either Xpac (I have crafted Dr. Boom). Is sticking with classic to try for Ysera/the Giants/Doomsayer/Harrison Jones or any of class specific legendaries I'm missing (Cenarius/Archmage Antonidas/Lord Jaraxxus) or should I go for something else? 

For the record I like to play all the classes.

Almost every classic pack I open is an insta-dust. btw

I'd go for classic packs for the class legendaries, you could always craft cards from the other xpacs with the dust anyway

I'd go for TGT, you lack some probably useful common cards, as well as many legends from there, you'll probably get more cards to collection from buying TGT packs than classic packs. Dust-wise, all packs are equal.
