What league should I be in?

[bop1000]

I am a level 51 town hall seven. I attack with barch and dragons. I have a level 1 barb king . What league should I be in?

Any of the Silver leagues imo.
I'm guessing you're not a farmer if you raid with dragons

[Drewbiedoo]

If you use dragons, you can be in dragons league

I would say silver to gold is best bet and if you can its worth popping up to crystal for gem achievement

I am a farmer, but I just got dragons and I am kind of excited about them...I am saving for 2mil elixer to upgrade dark elixer drill...what league for that?

If your aim is to save elixir then I would recommend not using dragons for now

I recommend you barch, with no dragons. As a lvl 51 you want to farm as much as possible. Save all your elixir for upgrading troop levels. If you do nothing but barch- you will find the "sweet spot" in a league where you can 50% a base, and still make out well with loot. Likely somewhere Silver 2/ Gold 3. Save all your DE for your BK too.

But seriously, save the 25-30k per raid by not even cooking dragons, don't even cook spells, or else you'll just be temped to use them. Imagine saving an extra 50k-100k per raid if you did.

Clash on!
