As I said earlier, in a team game it doesn't take that long to pay for a T3 arty. The enemy team can come pretty close to getting their money back IN THE TIME IT TAKES FOR YOUR YTHOTA TO CROSS THE MAP, its literally like one minute's worth of eco in a team setting if you're talking about a 4x4 where everyone has 300 mass income.
You're complaining about units that need to cross the map while assuming that when the artillery is completed, the artillery immediately kills stuff. It needs 20 seconds to even target, then three shots to kill a shield. On top of this you're assuming that the person who built the artillery will have his entire base protected against whatever is coming for him. Or in case of a 4vs4, that all players will have this right after the artillery is finished. It's more likely that all players defending against the arty will get enough shielding up as the shots come in, due to the artillery's RoF.
I didn't hammer on this all that hard, its not worth squabbling about as far as I'm concerned, but the point stands that the rei sa 44k mass disparity between the two teams in shield costs, and in a 4x4, that would be a 176k mass cost (44 x 4 = 176).
The player who is going to build the arty also has to build shields to protect himself anyway, that amount to 30k mass. And the player who has to defend against the arty also has to build shields anyway, to protect himself against stuff before the arty comes along. Like bombers or a land push. That player sees the arty, and builds extra shields, to a total of 48k mass. The difference is 18k mass, not 44k.
What part about an equal-mass situation do you not understand? Feel free to think "oh the arty player doesn't need this so he can have the arty done earlier", but at least understand that if you're going this way, so am I. So your arty base has no 30k of shields? I'll have a bunch of bombers that will take out the arty well before it's finished. You're using all the mass of all the players? So will I and then I'll have a much larger land army than you to kill you with it. Needing 10 UEF T3 shields for defense while building artillery is absolutely worth considering.
And with defenders advantage and a much smaller mass disparity in a 4x4 than in a 1x1, the Ythota would likely not result in enough damage to punish the T3 arty's builders. Again, its 1 minutes worth of eco late game in a 4x4.
Also, you have to admit that's a lot of shields. =P
No, it's not.
Again, 44k mass x 4 players = 176k mass. I just took the difference in mass spent in shields between your two bases and applied it to a team situation where one entire team has to shield up to defend from the arty.
Now that I figured out how you came up with 44k per player and told you how wrong it is, we can work with the new number. 18x4=72k. To be impenetrable against one artillery and hold quite well against 2 (only a bit of assistance needed)
Again, Oh yeah, with SCU assist you can definitely stop T3 arty, but in my testing its 300 mass per second to keep one ED4 up with engineering SCUs and it take 4 SCUs to keep the shield up. I tried it with three and they just fail. I suppose its less if you use multiple shields, but if memory serves 2 T2 engies spending 40 mass per tick aren't enough to keep two ED4s up.
Then you're doing it wrong. Don't assist. Build a new shield next to the old. The new one will not collapse at the same time as the old one and by the time the new one does collapse the old one will be back up or you'll have a third one. After that, the shields take it in turns and you don't have to worry about it. This whole setup is even effective against two artillery, as I have shown by adding shields in the attacked spot. There I still stayed below the mass cost of the artillery base.
This setup starts to be in trouble at 3 artillery, and there it starts becoming a good thing to assist one shield with 16 hives, or 16 SCUs. Don't powerstall and you'll be ok for a while, but eventually you'll collapse. As you should because you let your opponent get 214k mass in artillery and didn't do a single thing about it.

Now you're just trolling. This is about army vs arty and you already disproved your own theory by having only a fraction of bricks kill the arty that attacked, so you say (and didn't show). I have shown exactly the same thing with 100 harbingers vs 200 harbs worth of arty mass. The harbs were effective
without micro and now you're going "Oh yOu SHOUld Have mICrOED them". Against what? The bees in the air?
