Can I ask one last question...which area will have a dragon I can tackle at level 12ish or do I need to build a few more levels before tackling the next one?regardless of dragon Storm Coast is on deck
Ask as many questions as you like.
Check
this page out! It has all useful info on the dragons you may want - level, loot, location etc.
Anyhow, I recommend tackling Crestwood dragon first - I killed it at level 11/12. Brought Varric [DPS], Solas [combo/support], Cassandra [tank] and my mage[DPS]. Be sure to bring health regeneration potions and micromanage your party during the fight, especially the squishy Varric. Fade Step and Barrier are a MUST in this fight or in any dragon fight in general.
You can also bring a second tank instead of a mage if you want. Generally speaking in later parts of the game you can be three levels behind any dragon/boss/rift and still take it out, no problem.
EDIT: By the way. If you're playing on normal you will soon discover that if you spec your tank the proper way you will become practically unkillable. Dragon fights included. Hell... it's pretty much the same on hard. Cassandra/Blackwall [his chamption specialization is soooo good] can hold the attention of multiple enemies while you and the rest of your buddies do all the damage. Rogues can be real powerhouses, Cole and Sera especially. Varric is not bad as well, but his specialization is not as powerful. Doesn't matter to me, I bring him everywhere anyway
Mage Knight Enchanter can solo the entire game by himself, but in my opinion is horrendously boring to play. If you have dragon problems just bring Vivienne with you.
