Posting what Era you are in would help the discussion. (I am in Venus in three Worlds with on average A2100/D2300 )
With the OP percentages of boost I would assume the op here is in SAAB, Venus or Jupiter Moon.
The limit is what can be fit in the space allowed. Plus Great Building boost tends to be limited to well below level 200 or so. I would guess a max attack of 3000 could be attained. There are Attack Boosts of 2500+ now. 3000+ Attack army defense might be in the realm too?
The real test is in GbG where Max attrition is the key to what can be done.
The Defense will always have (no matter how high) the fact of minimum one chit of damage per strike from an enemy. And who goes first matters a lot. Particularly with "Keen Eye" boosts getting higher each Era up. So IMO Attack army defense can really never be enough. once you are in Eras with Keen Eye.
And neither can attack reach a level it can not get any better. And is your ArcticOrangery high enough to provide a lot of one shot kill when with Keen Eye?
So I say just by belief, no proof, there is no limit to a higher attack boost being of value.
But tradeoffs in what a player wants from the city may make higher attack boost less desirable than perhaps some other option? The 'diminishing returns"
Being able the trade i some of the bits and pieces of attack for better bits. is (or should be) an ongoing process in a city.
I am in SAJM as well and am at 2429 att but only 1410 att defense. The attack is easily doable but the defense for attack is much more rareIN reply, i am In Jupiter. I am still working to get my A/D higher, but not sure how much it helps. I would like to see numbers as shown by Trobb..99.1% chance of max damage, and what that percentage of damage is to each unit. That would give me a better idea. I am trying to get both A and D to 2500..not sure if possible with the space allotments..but willing to take out TOR and Space Cruiser if I get close enough LOL

If you are willing to spend Diamonds, a whole host of Sentinel Level 2's will take care of the D number with ease. You use the most efficient building in the game for D as well as space management. I run over 170 of these buildings and am in Progressive.I am in SAJM as well and am at 2429 att but only 1410 att defense. The attack is easily doable but the defense for attack is much more rare
That is what I hoped for in this event . 30 tickets bought for the SO and zero dropped over having it twice this event. Not impressed.If you are willing to spend Diamonds, a whole host of Sentinel Level 2's will take care of the D number with ease.

That idea is big in one of my Guilds. And the claim is fewer losses of troops. I disagree however.I cant confirm or deny but i heard a few times over the past year or so that a 72,5% of attack for attack def but im not the guy to do the math required to find out. I definately agree that lvl 2 sentinals in bulk is valuable.
