When I hit TH10 I used to raid with healer,Gaint,wb,archer,goblin,barb composition.
I farmed in gold II. Loot was horrible and after I while I decided to try Barching and move to higher league for the league bonus. Never regretted my decision. Even if some days the loot is dry i can still go for 50% and get the 140k/140k/900 league bonus (I'm in master I).
One of my royals are always on upgrade so at the moment my attack composition is:
135 Lv7 Archers
105 Lv6 Barbs
5 Lightning spells
BK or AQ
Totally manageable with 120 Arch / 80 Barb / 4 Lightning spells / AQ or BK (What I used as a fresh TH10)
Some people might argue that the game gets boring if you only barch and I can agree. But I do clan wars 2-3 times a week, and there I get to use different army comp which makes the gaming experience more fun.
I'd like to add that I never buy gems for boosting/upgrade etc.. I collect gems from rewards and i usually just boost my AQ or BK + Spell factory (sometimes) on the days that I raid a little more.
