I started playing this game about 2 months ago and read your thread about your premie th7/8/9 journey two weeks which made me decide that I should also go ahead and upgrade my th7 to th8 since I had already maxed all my level 7 walls as a th7.
I am now a th8 and I must say the loot at 1300-1500 trophies absolutely SUCKS! I used to raid 2-4m gold per hour as a th6/7 at 800-1100 trophies. In fact, it took me just under 6 days to max all my th7 level 7 walls and still had a lot of gold and elixir to max barracks e.t.c. I used to use the giants, healers, wallbreakers, archer and goblins, but since arriving at th8, I have a 50% loot penalty against th6 so I avoid going below 1200 trophies because I know I will find a lot of th6 noobs there but because of the 50% loot penalty, I will end up pressing next for 10 minutes. I no longer use my giant/healer strategy as most of the people I find now are th7/8s with an extra AD. Which means I must now use my level 4 BARCH strategy.
I followed your advice and as soon as my th8 upgrade finished, I upgraded my labs immediately and as of now it has under 24 hours to complete. My BARCH are so weak against level 8 that I just end up pressing next against most of them. The th7s are also pretty strong against my BARCH, if they have a compartment base design which means my barbs will continue futilely slashing against the walls while the WTs and mortars wipe them out.
I rarely find any collector raids at silver 1 - gold 2-3. If I do, it's the equivalent of Christmas for me as it's just so damn rare. I don't attack anyone below 130k gold as waiting 10-15 for the troops I queued in the barracks to finish training is painful.
My current army composition is 70 barbs (level 4), 88 archers (level 4), 6 giants as tanks (level 4), 6 wallbreakers (level 4) so that stupid barbs don't slash useless walls while mortars and WT obliterate them.
I still struggle against compartment style th7 bases with loots in the storages and I have to sometimes spend 50-100k gold pressing next until I find a good base at 1300-1500 trophies.
I'm in desperate need of help as farming gold has not been a problem for me before and I could easily max my walls in days, now I only farm 1m gold per hour, and that's with boosted barracks too. Any USEFUL input and suggestions would be GREATLY appreciated!
To give you an idea of how proficient a gold farmer I was prior to th8, I started playing this game around 28th January 2014 and I have hit 103m gold grab and 67m elixir escapade
