I have never been to masters (and am not TH10) but I found in C2 having TH outside was best anyway and not sure why more people don't (for farming).
I was a new TH9 so only had TH8 defenses and would only ever get my TH sniped which worked out great since I never lost resources especial considering I was always offering the max in my storages.
Normal process was
- Look for a base if I see any exposed TH’s snipe them for bonus and a few cups
- Attack a base usually get 2 star sometimes 3 and gain 200k+ gold and elixir, 1-3k DL and 12-32 cups
- Log back when army was done and often find TH had been snipped (sometimes it hadn’t) and lost 4-10 cups and 1k gold and elixir
- Repeat over and over
I may not have been in masters but I could easily be 3 stared and think having the TH outside saved me a lot of resources not to mention the cost of re arming traps and having to re fill CC.
I don’t think we could ever get enough people to do this but the more that do the better the game will come for all. Remember the more loot that is generated the more profitable raiding will become. There are two ways loot is generated collectors and league bonuses. If everyone actually left their TH’s exposed a lot more loot would be generated through league bonuses meaning a lot more available for raiding
This would be a th7-8's push be amazing with all the extra th's outside, still won't work since forums is only 1% of clash or something
