There’s four specific ways I’ve seen commanders try to take east and west keep in the BL’s (excluding golems and trebbing) that I want to bring up:
1) Ramming both outer and inner
2) Catapulting both outer and inner with the same catapults, using all supply (ninja spot they call it)
3) Catapult outer with most of the supply, build more catapults on inner and catapult the inner with both your inner and outer catapults
4) Catapult the outer, catapult + ram the inner gate
Countless commanders have called me stupid for saying that 1) is quicker per supply than 2) when comparing superior catapults to superior rams.
Most will say “It is better to just catapult the walls because you can place the catapults in a spot where it can hit both outer and inner walls so it is more supply efficient for the damage it does.” All of them saying this without actually knowing the dps that the siege does and how much hp the gate/walls have.
When comparing superior rams with ram mastery to superior catapults with the r1 mastery that gives 20% more damage to walls (most common rank among catapult users): superior rams beat out superior catapults for all accounts. For 100 supply and up where you can ram both outer and inner, it is quicker to just ram. This wasn’t true before ram mastery but with ram mastery now, it’s faster to ram.
1 sup ram outer and 1 sup ram inner: 3.3 mins in total for both gates to go down
2 sup catapults that hit both outer and inner: 3.78 mins in total (1.35 outer, 2.43 inner)
As you can see, rams are much faster and that’s comparing 100 supply to 120 supply.
3 sup ram outer then 2 sup ram inner: 1.36 mins (250 supply)
5 sup catapults that hit both outer and inner: 1.51 mins (300 supply)
Still better.
I calculated 3) and 4) too. For 3), it’s pretty close to 2) for a lot of supply counts and very slightly faster at 300 supply but still not worth it due to time to build (because it’s only around 3 seconds better at that supply).
4) is a little close to 2) for low supply but is never actually faster per supply.
For 3) and 4), there is of course controversy as to how many siege to build on outer and inner. I calculated the optimal siege through just playing around with numbers which go up until 600 supply.
IMPORTANT:
Guild catapulting both walls is better dps per supply than ramming on all accounts. This comparison was comparing superior rams to superior catapults. Many commanders still believe that superior catapulting is better dps per supply than ramming which is wrong.
NOTE:
Double catapulting the walls is generally safer than ramming in regards to avoiding enemy siege, especially if the enemy has siege on inner and behind gates instead of the area where you want to catapult from. Thus, it’s perfectly fine for a commander to double catapult with superior catapults, particularly if the enemy server is trying to defend the keep. If you believe that the enemy server is not defending the keep you are after and has no siege, I’d highly recommend ramming.
tl;dr ramming EK/WK is faster dps per supply than double catapulting outer + inner, double catapulting should only be done in response/fear of enemy siege and not because you think it’s faster (because it’s not)
