Please bring goblin level 6, wall breaker level 6 and pekka level 4 to townhall 9
I am a town hall 9 player and I have been staying at town hall 9 for about a year. Now I have 170 level 10 walls and 80 level 9 walls. Barbarian King level 25 and Archer Queen level 27. No gemming at all. Therefore, you can say I am a pretty experienced town hall 9 player.
The reason why I want goblin and wall breakers level 6 at town hall level 9 is very simple: level 5 goblin and wall breaker are too weak and useless when you attack people at the same level. They can be one-shot killed by level 7 wizard towers. Also, it takes 3 wall breakers to break level 9 walls if no rage spell is applied. Therefore I think it would be sensible to bring level 6 goblin and wall breakers to town hall 9 and get level 7 ones at town hall 10.
The reason I want pekka level 4 at town hall 9 is not only level 3 ones are weak for town hall 9. When you get to town hall 10 you need to upgrade pekka twice in the lab, while it cannot be upgraded at town hall 9. Also, level 4 dragon is brought to town hall 9 as expected, I think pekka should also be the case.
