Should I start rushing to th11?

Should I rush to th11 and make my base a engineered one?

My king queen are 15 and I'm a th9
With defenses upgraded and walls pending

I'd stay at 10 for a little while and get your troops up to scratch for war/farming/both depending on what you enjoy.

Also up your heroes a little at 10 before jumping to 11, even if you're engineering a TH9 minimax :)

it gets a lot harder to attack at Th11, if you think you are good enough and can patiently wait for a base, and can get the warden to 5, I would do it

Strong troops are key especially if you war

Upgrade your HERO to Adults.
Then make this huge step.

if you can be sure that you will be upgrading heroes always while in there. Go ahead.

What's your farming plan? upgrade plan? war plan?

Yes....upgrade your troops to be able to attack at TH 11 and then start maxing your defenses as a TH 11......get to the end game (currently TH 11) as fast as possible and then start maxing your defenses while waiting for TH 12 to be introduced to the game.

I will just upgrade my heroes and troops with walls of I start rushing
