Lvl 9 walls or nah?

I'm a townhall 9 with pretty much maxed out defenses and all lvl 8 walls , should I grind out the Legos for a few months or upgrade to townhall10?

Have you maxed out your attack?

Yes, all maxed for th9 , except golems & hogs

Heroes as well?

Do what you feel, if you're playing the game patiently, then do lvl 9, if you're ready to move to th 10, then move on. If you think you'll want lvl 9/10 walls tho, I'd do them now before the harder farming and loot penalty at th 10

I went to TH10 with maxed D and lab in TH9. Walls were 8, heroes were 15. Glad i didnt grind out Legos, though they are likely very easy to do now that elix is an option.

Up to you, but I felt 250 mil gold was better spent on defenses rather than +1k HP to my wall segments.
