Upgrade to TH10 or wait?

I have primarily concentrated on defense's never leaving a builder idle since th8. Just recently I realized that I have been kinda slacking in the hero\wall department. So soon I will be hit with the question of upgrade to TH10 or play catch up on my heroes and walls?

P.S All of my troops are not maxed but the ones I use in my army compositions are. Also I have no problem using Bloonians on th9's without heroes. Idk if this should affect my decision.

Not sure how to post pictures but all lvl 7 wall's lvl 8-9 for intersections lvl 9 heroes going to 10. 3 archer towers 2 teslas and one cannon to go up one level each.

I would say wait. You still have a lot to do

No, Max your base before going to Town Hall 10. Its better to do it now with better loot then with less loot percentage. I would get all your walls to at least Lvl 8, and some Lvl 9 walls. Heroes should also be worked on

I see and I agree but at what point should I upgrade?

Thanks for the advice. Not looking forward to idle builders but I guess it was inevitable.

Get at least lvl 15 heroes and lvl9 walls. Max out all your troops too, you never know when an upgrade will come along that will buff a troop you've never upgraded/nerf a troop you use all the time.

All walls lv8, all buildings/def fully upgraded, heroes both lv 15 would be a good spot. You can go earlier, but it just makes it that much harder.
And all troops maxed too.

I would suggest waiting. Firstly, because you still have quite a bit of work to do(I strongly believe in maxing Town Halls). My other reason is that loot has been a bit of a problem lately. It may not be for you, as I can not speak for everybody, but if you go to Th10 it will likely become even harder to obtain than it already is. Choice is yours though!

I see lvl 8 wall's should only be a few weeks but lvl 9 is another story. Does it really make that big of a difference. I have never hit higher than crystal II so I guess I wouldn't know.

You should definetely wait, despite what some people say it is undoubtedly harder to get loot after the update, especially for th10. Walls are much easier to get at th9 so focus on them and all your other buildings but de is easier at th10 as u get an extra drill and stronger troops. It might seem like a grind for walls but it will be worth it.
