Here is how to fix th10 loot
Your solution for th10s is to go up in trophies is simplistic and is a solution only for hardcore farmers who can stay online for hours at a time... And Barch with cheap armies.... This is not a new idea. It is in fact what most people are doing. The issue is NEXTING through dozens or hundreds of empty bases with little to no loot in them.
Your example of taking 80k gold bases does not factor in nexting costs which are usually covered by the league bonus, so lets call that a wash. If i am saving up 7.5 million gold or elixir and making 80k a raid, how many raids and how many hours of barching is that? You also conveniently ignore defenses and resources lost. If I have full storages for 2/3 of those 100 raids I am making for a single upgrade, how long will this take? How much resources will I lose every time I logout? Is this fun?
You can do all the fixes you want, until loot is added to the TH, high level bases understand that an outside TH is almost a guaranteed snipe.
1. Add some loot to the TH. Make it equal to a gold/elixir storage
2. Do something with nexting cost so it doesn't disappear into nothing
3. Lower trap re arming costs, current loot does not warrant 200k plus rearming costs, it's really crazy high
4. Make defense wins mean something other then the privilege of re arming overpriced traps and useless trophies... If manipulation is the concern then add a % to it so ppl cant drop 1 troop and give bonus
5. Increase collector output 25% or more
6. League bonus multiplier... 2* worth more then 1* etc... Reward bigger accomplishments
7. Further discourage bots, any activity by them is too much
8. Elixir for walls needs addressed.. Either make it so only elixir above X amount can be used for walls leaving some elixir for theft, or make only lvl 10+ walls for elixir, or some other elixir solution
Do those things and th10s will immediately start seeing full storages in their queues again and people with near maxed defenses like me will break shields again and probably put our townhalls inside
